tt-rss main UI is designed with proper PCs in mind with fitting information density and control methods i.e. hotkeys, i’m not going to make it into some kind of web 4.0 abortion targeted at touchscreens like most “modern websites”. there’s definitely not going to be any swiping.
as far as i’m concerned android-specific UI is a needed compromise because devices are slow, have tiny screens, and no keyboard.
luckily there’s a variety of mobile web UIs for tt-rss, you can investigate those and see if they fit you better.
