I hope you don't mind mischamajskij , I forwarded your screenshot for the Audacity developers to have a look at. It has received very positive comments.
Because themes inside Audacity exist as "code", they are under the same license as the rest of the code, which is "GPL v2 (or later)". I'm not an expert on licensing, so I'm not sure if "CC-by-SA 4.0" is completely compatible with GPL v2 - I don't think it is. It's my understanding that everything shipped in the Audacity code has to be compatible with GPL.
If the developers wanted to use your theme, would you be willing to extend the licensing terms to allow it to be used in GPL v2 software? (You retain the "copyright" on the theme regardless of the license terms).
Well what to say, I'm so happy with this!
What was worrying me was that DarK icons are released under CC-BY-SA, which enforces me to release my derivative work under the same license.
However, I've done a little research and it turns out that CC-BY-SA 4.0 is one-way compatible with GPLv3 since 2015.
Please have a look at this page
The key passage is the following IMO:
Put simply this means you now have permission to adapt another licensor’s work under CC BY-SA 4.0 and release your contributions to the adaptation under GPLv3 (while the adaptation relies on both licenses, a reuser of the combined and remixed work need only look to the conditions of GPLv3 to satisfy the attribution and ShareAlike conditions of BY-SA 4.0).
I think this means that if I put my own contributions under GPLv3, the ImageCache.png file "relies on both licenses", but the Audacity team, as a "reuser of the combined and remixed work", can release it under GPLv3.
I hope I'm right in assuming this, please verify carefully.
In any case, I'm glad to license my own contributions under GPLv3.
Here's the file with updated license terms.
