Yeah I didn't want to throw out too many specifics to my reply. Happy to elaborate more.
The UI is very busy and makes me anxious having that much jammed into a screen. It's trying to do a lot all at once. I'd like to be able to just rearrange what is on screen, or scale back sections to an icon instead for example.
The main section with the feed in PleromaFE is especially intense. Tight fonts and lots of icons. Clicking on a post expands that thread, but I'd much prefer to have a break-out section where highlighted or expended content can be viewed instead. A second column for example, like the advanced web UI on Mastodon.
Indeed that UI is a very effective and useful way to setup a screen, in my opinion.
Overall, the PleromaFE UI feels very dated. 90s dated. At the other end of the spectrum is Soapbox – very clean, and somewhat lacking in features. But it's a calm space and the UI is nicely responsive. It's very smooth. Maybe some inspiration to be found there.
Those are my thoughts!
