While in the process of developing numerous GUIs for my current project I came to a realization, that the development toolkit leaves much to be desired when it comes to GUIs.
Suggestions:
Justification options for GUI elements. (Can be done with simple math taking the width/height properties of the GUI and the width/height properties of the individual elements into account)
Multiple selection of GUI elements.
Alignment of multiple selected GUI elements.
Equal Spacing of multiple selected GUI elements both vertical and horizontal.
Lock GUI elements to prevent accidental movement/resize.
Snap to grid of GUI elements.
Keyboard movement of GUI elements with arrow keys for single pixels or ctrl+arrow keys for tabbed movement.

These were actually implemented in the old editor before moving to V3.
Now, GUI elements may move out of place whenever you click one of them, which is very annoying. :(
I agree that all these suggestions would be useful, hopefully I'll have some time to implement them at some point.
