Way to select only certain types of objects
I think there should be a way to select only object of a certain type. For instance, when the Point tool is selected, using the "Select All" command would select only points. When the Segment tool is selected, only segments would be selected.
I know that you can select all objects of a type in the object tree, but this does not distinguish between visible and hidden objects.
Additionally, adding the ability to drag-select using the mouse and only select objects of the selected type would be great as well. The SHIFT + LEFT MOUSE key combinations could be used for this.
