First of all, great job, this is now my new way to browse Lemmy on Desktop :)
I would like to make some suggestions for you to consider:
Infinite scrolling, instead of pagination
On Sidebar, present the instance / community mods (like in the OG lemmy frontend), being these ones clickable to go directly to their profile (useful to send messages to mods)
On Sidebar, have the same markdown as Lemmy OG on the instance / community text / description (bold, italic, etc), since today everything has the same formatting and it's harder to read
