Personally, Spaces is one of the nicest chat-organization tools I've found in an app so far. I can finally group things how I like, have duplicates, and share groupings with other people. The fancier stuff with Spaces isn't super trivial, but the basics work by just tapping obvious buttons on screen.

Sub-folders would be even better for large-volume stuff like throwing multiple Discords worth of things into a Space, but I don't currently need that.

E2EE I have routine fights with, so yeah - Element is not great yet. But it's good enough that my siblings and I are seriously considering converting us + my non-technical parents over, now that Hangouts is horrible and we all hate how flaky it is. And it's a much, much better experience than Signal. The only other contender at the moment for that migration is Telegram (which is absolutely stellar, they're doing an amazing job).
