Thanks for adding this, and for the test coverage. I'm not sure if that's the best way to handle it here (the track popup is at least self-contained), maybe it would be better to make that whole menu its own component, with the input dialog and whatnot. For this PR, it's alright, so I'll merge it once the CI passes.

[sferra]

I thought about extracting the pop-up to a separate component, but I decided to first add the functionality and leave the refactoring decision to you.
How do we address code base improvement and cleanup/refactoring? Are there specific issues (types) in the tracker for this type of task?

[nukeop]

Not really, I do that whenever I feel like, or when I'm working on a large feature (like the local library scanner) and keep seeing untidy code. Sometimes instead of working on features I just look for stuff I neglected to do earlier and work on it. If I do any refactoring though, I make sure that area has decent test coverage to avoid regressions. Any such work is welcome but I realize it can be boring by itself, so usually I do it myself.

[sferra]

So would you accept refactoring PRs? I usually try to strictly separate refactoring from adding new features, to avoid regressions, specially when I'm not very familiar with the code base.

[nukeop]

Sure, I would be very glad to see that. Typically I'm the only one doing that.
