Feature request: Add more themes (or allow user-customisable themes)

[Willicious]

Hi! I've finally moved over from SourceTree to Fork, and it's so much better and seems more stable so far. One thing I miss from SourceTree is the navy blue UI, which is slightly easier on the eyes.

I'm not sure how possible it would be to add complete customisation of all UI elements (ideal), but a few more theme choices might be good (if Fork is open source I'd be happy to do the work myself and send a PR).

To be a bit more specific, I'd probably prefer blue-on-grey rather than orange-on-grey for the active branch (a setting for this alone would be good enough), and maybe different colours/shades for the icons at the top to help distinguish them from one another.

This is probably the only thing I'd suggest. Everything else seems great!

Themes in Fork are hard-coded and can't be customized:

Themes in Fork... can't be customized:

Yes exactly. This request (and the other requests you linked to) is (are) suggesting that themes in Fork can be customised. If the answer is "no", that's fine, but there clearly is some demand for this feature so you may wish to consider including it.
