Really enjoying @pachli as my Fediverse client. It's really making me use the platform.
From a UX perspective, I have just one gripe. If you're at the top of your timeline and you swipe down to refresh, you have no indication that there are new posts. Natural action is to swipe down to see if there are any new posts, which can then result in another refresh.
Rinse and repeat.
Either a lozenge at the top saying "New posts" or bringing the timeline down by a couple of pixels would be perfect.
