I don't tell here about fantastic things and super-wishes.
What's real and need (for comfort):
1. Player - Go to Different Room / Character - Move Character
Mini-picture of new room and choosing coords by mouse-click (put flag). Graphical and comfortable. Like "Teleport..." in RPG Maker 2000.
2. Copy/Paste for Commands and Multu-select of them (very comfortable!)
That's all! :) I think, it's very easy.
Thanks for your input, however the Interaction Editor is being removed in AGS 3.0 so these are unlikely to happen ;)
