I'm biased because I chat a lot with the developers, but I'd highly recommend Thunder - very sleek, very customizable, VERY nice compact mode, and a very welcoming group of people. If you try it and feel like something big is missing, they're quite responsive on github! Been quite impressed with the leaps they've made with features on every release.
Thunder does look quite nice, but sadly my long defunct keyboard app doesn't work with it, and they weren't able to get the apk to test a fix for it. (But they did try.) You'd think, of all things, a keyboard and input field wouldn't have compatibility issues, but I guess that's Android for ya.
I did submit a bug report, but the dev didn't seem interested in getting the apk for testing. I can't say I blame them. Apk sites are a little sketchy, and it's also probably not a bug that'll affect many other people.
Yup. I've configured my thunder to look and feel really similar to the way I had Relay set up. The compact modenis great and the customizability is really good.
Give it a shot! Definitely check the settings if you do, the tweakability is fairly expensive - and if anything feels missing let the team know on GitHub!
I'd use Thunder more if they had mark as read while scroll, and hide read posts (I think they already have the later) if these requests are outdated please lemme know.
"dismiss read" is an option you can add to the FAB, and mark as read on scroll looks to be a setting now as well! Haven't used either, but hope they meet your expectations :)
