Matty: great

I wait anxiously for the next major release

(because installing 2 versions on one computer is... inadvisable)
Crimson: True true; you could include a test picture with the editor (mask_test.BMP), with the first 15 colours shown exactly (like a tv test image), and saved as an 8bit RGB .BMP image? This would be a much simpler solution and would save everyone the hassle of having to create and save an image of an exact specific type.
Actually... there are some things that get me about AGS, namely the regular no-backsies choices.
For example... everything in the Room Editor.
Change the position of the character? Wanna change it back? You can't.
Change border position of walk-behind cut-off position? Oh well, you're screwed.
Change the background of the room, then realised the original was the only copy because you changed it, deleted it, and forgot to export it? You're done.
This results in me keeping copious amounts of backups - could we have this with the undo list applying to the room editor, and not just the text script editor? And any other no-turning-back parts of the Editor?
Please remember: I'm fully willing to pay. One other thing that we could use a change with, that would lessen development time by a factor of 50.
