This is the development version, this is work in progress.

Note that I made no guarantee about the style name of the themes. All 
what on you said on the forum were your assumptions, even if they seem 
logical.

If I understand what you wrote correctly, you use the background color 
of the editor to make the distinction between the file types, the 
"Background" style of the theme being used by the TextEditor instead of 
its background color.

But:

- I found no good reason why the background of the editor should not be 
prioritary.

- I wanted to avoid the problem I see elsewhere of having to write 
themes twice, for light and for dark backgrounds.

Sorry if it broke your programs, but it's difficult to be 
backward-compatible with that subject, especially if, as I said before, 
I made no guarantee about the style names. They are entirely dynamic.

Maybe I can implement a mandatory default "Background" style in the 
themes. If you set its color, it is registered, and if the TextEditor 
sees it, it will use it instead of its background color.

I will see what I can do...
