Line numbers need more contrast

[babaissarkar]

The line numbers are not very readable in most themes. Possibly they need more font weight or a contrasting color.

Version: latest checkout of #988. (694eb0c) Should be reproducible in master as well.

Thanks @babaissarkar for your attention to detail!

This is a known and widespread issue across most themes as you've correctly noted. In fact, contrast is an issue with some of the syntax highlighting palettes too.

Note that the way themes are implemented is not exactly ideal in its current state (@Stefterv can tell you more) and refactoring it to use Jetpack Compose is part of our long term roadmap.

However, since this is a matter of accessibility, it might still be worth fixing in the legacy system. Feel free to give it a go.
