I will likely ditch Vivaldi for this one tab groups gets implemented. It has all the features I need and I’ve been looking for a non-chromium browser to switch to for a while. Floorp was close but missing critical features. Zen is very exciting for me.

Someone already mentioned Logseq, but I’m really enjoying Obsidian for my note taking needs. It’s similar, but I have found Obsidian to be very nice. Not FOSS, but I really like what the devs are doing.
