Hello!
First of all, GeoGebra rocks! (Whenever I make a feature request, I always feel compelled to start with a disclaimer that I love GeoGebra and I'm not at all disgruntled.)
It would be great to show TWO Graphics View panes next to each other, left and right, with the vertical bar down the middle that you can drag to resize the panes. So, this "extra Graphics View" would behave just like the Algebra View and Spreadsheet View. Any drawing object would belong to only one or the other, but not both. You could show/modify axes independently in each pane.
Two applications:
1) Putting all controls and text into one pane and all drawing objects in the other, so that they don't interfere with each other and the drawing does not get cluttered.
2) Showing connections between two different graphical representations, for example, between cartesian coordinates and polar coordinates. As another example, you could have the input to a complex-valued function in the left pane, and its output in the right.
I've included two "proof of concept" applets, and an example screen shot. Thanks!
Marc
I like this idea 
As Rush Limbaugh listener would say, MEGA DITTO, great demos...Great idea Marc, add this to some of the other feature requests like independent spreadsheet windows, independent windows, and tabbed pages.
I believe this was done using panels, some might say that GG already does what you request and these others because it can be demonstrated, but I know that you want the ability to split the screen more intuitively as in the TI-Nspire and Geometer's SketchPad.

Hi Marc,
Great idea - as you may remember, I am facinated by polar functions, so this demo caught my attention! The panel idea is easy enough to implement for demonstrations, but I can see value for two graphics windows for hiding solutions to problems or explanations. (Not that I have yet exploited all the facilities that GeoGebra already has, by a long way!)
Just a query (for anyone to answer) - I thought it would be good (and easy!) to 'trace' the path of point B, but switching 'trace' on doesn't seem to work. Am I missing something?

Hi folks, thanks for the replies. I was thinking some more about this. What I really want is a way to place controls/text so that they don't interfere with the graphics. I would be very happy if I could just draw a rectangle with absolute position on screen; then controls could be placed on top of this. (Of course, that's what I do now, but it involves the Corner[] command and it's not easily moved/resized.) If there are only a few controls, then this wouldn't take up as much screen space as a whole new pane.
If GeoGebra ever did introduce a second Graphics View pane, then it would have to be clear which pane had focus so that commands from the input bar would know where to place output.
Marc
There are several devices that have similar features like this already. The show the active pane in a similar manner by showing which window is active currently. Actions in either window can provide results that changes the other window with variable names that are used in both panes. It is a great idea, do not down play it. It could be expanded to go across multiple tabs similar to capabilities in SketchPad and with the TI-Nspire.

Hi
Without glorifying TI Nspire, I have to admit that the possibility to connect a spreasheet, coordinates, a CAS and a text document is very interesting.
So, I do not care where a good idea comes from.
On the same way, people who use(d) TI Navigator can say it is a wonderful tool and they probably would like to get a collaborative Geogebra.
Tony's idea (as Acron's one in http://www.geogebra.org/for...) is a good one, and that s the most important thing :D
Laurent
Ha! I had to laugh at Noel's perceptive (if off-topic) remark. I fully agree with Laurent's view - good ideas are good ideas no matter where they come from. I actually have no familiarity with TI Nspire or Sketchpad, but it's good to keep an eye on the "competition."
Any other thoughts on the 2 Graphics View panes idea? Pros, cons, applications, skepticism, etc... ?
Hi Noel, Marc
I'm still puzzled about why the trace of point B (layer 5) doesn't show unless you put the fill of the panel (layer 0) to 0%.
(not on topic!)
Must be too close to the end of term - my brain has stopped working!
Kathryn
It is not my intent to glorify either of these products...these are products that have some good ideas and multiple faults.
SketchPad is over 10 years old and the company is struggling to upgrade there product to be able to compete with GeoGebra (from some of their avid users.) The TI-Nspire is a handheld computer that looks and works like a calculator. I would rather use GeoGebra, but I am forced to learn to use the TI-Nspire by pressures within my educational region. I actually have my students use both GeoGebra and the TI-Nspire in class and they mostly use GeoGebra outside of the classroom.
I will soon be getting the TI Navigator for the Nspire and I must show usage. Most of my activities are made to be used by both GeoGebra and the Nspire when possible. I will be giving a talk this summer at a mathematics conference comparing them. I am sure that TI will be there (they visited me last year) and the company that produces SketchPad will likely come as they are struggling with the Nspire and GG technology.
Tony
PS This comparison may be the topic of my dissertation in Education Technology Management.
I would not have a problem with a collaborative GeoGebra.
For some reason, I am being blocked from reading Laurent Hivon's reference.
I have no problem looking at any and all software to assist students in learning. I think that the purpose of GeoGebra or any other software/device that one can glean ideas and insight into the good/bad ideas of packages. I mention SketchPad due to its age and the Nspire due to the power of TI. Both of these programs are well known in the US and EU.
One thing that observing other systems is that one can improve their product. At this time, GG is the best overall package in quality and price. The two programs I have used to compare are commercial programs that are having problems keeping up with GG. Sort of like MacOS, Windows, and Linux. Everyone has a favorite and each has individual advantages/disadvantages.

Hi Marc and everyone,
Could you please show me how to put two graphics screens side-by-side as Marc did in the Cartesian and polar file?
Thank you so much for your help.
P.Y.
Open you "View"-Menu and choose "grafic 2".
I got that. But how do I put them together and assign a graph for each screen?
thank you for your answer.
P.Y.
First: read the help-wiki ...

Second Graphics View
A second graphics view may be opened using the View Menu. If two Graphics Views are opened, one of them is always active (either it's being worked with and it has bold caption, or it is the last view that has been worked with). All visible objects created by Commands appear in the active graphics view. For each object you can specify in which Graphic View(s) it will be visible using the Advanced tab of the Properties Dialog.

I agree totally except with the
I don't see why this restriction.My need is often a big zoom alternately on two points, in approximation processes,
which is totally unpractical by zooming in and out.
Alternately, have a list of a few "place and zoom" memories
which I could manage as "save" and "goto" any time
in a similar way to what is done in adventure games.
Excuse me for my english, I did not find the right topic in french subforums.
(they are still for version 3.2)
