Amazing app!

For a one-time payment of $64, you get an amazing markdown editor with ridiculous capabilities, customizability, and plugins from a great community. I’m use Pinch as a task/habit manager, databases for my classes, and I continue to figure out more and more ways to use it

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.
