When I was using Lemmy, I also preferred the web UI. It also does things that PieFed does not, like PieFed's search (like Reddit) is crap, but Lemmy's is superb. And I like how Lemmy can separate up from down-votes, bc e.g. +16 & -15 = +1 is a very different thing from merely seeing +1.:-)
But over time I simply became too frustrated with its very many limitations, a good fraction of which apps reportedly fix. Although PieFed also fixes them as well, and then some, while still offering a basic web UI. Check it out! But keep your Star Trek account too, and just see how easy and fun it is to use either one to accomplish something:-).
The chief reason I keep harping on this is that PieFed is written in Python, so is much easier for a community to edit, compared to Lemmy that is written in Rust, which is notoriously difficult even for those who already know C++. The pace of development of Lemmy is thus extremely slow, in comparison. But if it works for people then that's great, and yet for that audience all I can do is recommend an app to try to address issues such as these that otherwise languishing for months to years without being worked on.
