Added: Enhanceed MangaChapterListItem with focus state and visual fee…

[Troppy2]

This PR is meant to close issue #3239. The issue was about keyboard compatibility with Mihon and focus highlights.

The exact changes that were added were mostly in MangaChapterListItem.kt, which added a focus highlight (imports + isFocused state + drawBehind + onFocusChanged). I tested it on Android Studio to see if it worked with a keyboard, and I was able to use the arrow + tab keys, but I didn't do extensive testing.

Side Note: This is my first time contributing to this repo, and I have been using this open-source app for a long time, so I wanted to contribute to it. I don't have extensive Kotlin knowledge (mostly Java), so any feedback would be really appreciated.

Sorry about that, I hope the second commit fixed the formatting issues. I'll remember to run spotless when making new commits. Thank you!

I see you made some visual edit with that drawbehind thing. Do you have some example screenshots? Make sure to censor source names if they're visible.

Yeah I don't think the update I made did much though because I currently use the app and the features the issue was talking about I assumed was already in the app, but I use the mobile version I have no idea other use cases of this app outside of phones, and tablets.

I don't know how to show that I used my keyboard but if you click tab multiple times, it can scroll down and select chapters it highlights the chapter that is selected.
