Ideas !

-
Multi-touch gestures support for iPad
-
4K resolution support (1920x1200 is actually the max)
- Custom interface (ex : show/hide fonctions in "Action part" ; Dark color scheme ; Color of the background)
-
Menu in "Accordion" style (Especially for the "Action menu" !)
- Bigger points and lines in the "Way system"
- A crash reporter with the logs sending (maybe ?)
- Vis to remember the last window size when opening (full-size window at each start on mac is boring)
- Fullscreen App support (for OSX 10.9+)
- XBox360 Controller support (Yeah, it sounds stupid for Point&Click but it open the possibilities. Still no support on 2,5$ billion Minecraft which is Microsoft also...)
- Keyboard shortcuts layout... with shortcuts
-
Real-time player (modify the game while you play so you don't have to run the game each time you make modifications)
-
Sound FX engine (Real-time rendered FX like reverb/delay/compression/pitch/distortion/etc)
- Video "in-scene" (video playback inside a scene with custom size etc)
-
Use the mouse-wheel to increase/decrease value number of the selected parameter (by 1, 10 or 100 defined in option menu)
- "Turn before walk" animations ; "End/Start walking " animation
-
To-Do List section (with a "Checkable" case)
-
Overhaul iconography to navigate faster thru menus and options (and to look more awesome)
- Help section that redirect on Wiki
- Icon (PC/Mac) an cover of the game in "Game info" section (used when exporting the game)
