Hello
Forgive the post so early on in my membership.

Is there a way to change the colour theme of the interface?
I have found the output theme colour options but would like to develop TA's
without the glare of black text on white background.

Is there a way to develop Quest games using another ide such as Notepad++?

These and many more dumb questions are probably on the way

Cheers.

You mean the colours in the editor?

I believe this has been raised in the past, but can't remember if there was a solution.

If you're using the web editor, you could probably override the colours using a user stylesheet; although how you go about this varies between browsers.
On the desktop editor, I don't think there is such an option. If you can read XML, there's nothing to stop you editing your game in vim, Notepad++, or any other code editor; but this takes away from Quest's ease-of-use somewhat.

Hope that helps :)

(ONLINE QUEST) : In "Game" menu, simply click on "display" panel then you can change the "Background" and "text" colour to whatever you fancy.

Yes, but need to know the Quest coding VERY WELL or else you will create more problems than you solve.
