Add a proper multi-block block selection

I was hoping you will add a proper multiple block selection (like in Anytype) in 3.7.0, but I still don’t see it.

Please consider adding this extremely important feature.

Good app

Notion like app but also for offline use and more flexible.

Can’t sync with iCloud

Garbage App.
Can’t sync with iCloud.
Also requires you to pay for THEIR sync. App is also very clunky at best. I’d rather use Obsidian.
