Thanks Arathorn, I've now given this a try. However it's not nearly as compact as I would want. Especially the room list on the left, as it still uses the room avatars in this mode it will only show a pretty small number of rooms there. Making the font smaller won't fix that. When I move everything to Matrix I will have at least 50 rooms open at any one time (different IRC servers, whatsapp bridged, telegram etc etc) and I don't want to scroll too much.

Also, every time I have to expand the "Show xxx more" ones for each section, I can't just scroll to the bottom of the list. So that's an extra click.

When I mean a high density look I mean without avatars etc :)

Oh it does? I try Matrix on a yearly basis with all the bridges and I didn't see it last year. I'm giving it another try in the next month or so. Last time the bridges weren't stable enough yet. I didn't notice this feature that time. Thanks for pointing it out!

I'd prefer a light desktop client though. I didn't spend much time with the web version, perhaps this is why I missed it. But I will definitely give it a try!

By the way I understand the focus on consumer usability, as it's needed for wider adoption. I'd really love for matrix to become mainstream.
