They released an example for a block based text editor here: https://liveblocks.io/examples/block-text-editor-advanced/ne...
And as for CRDT and conflict resolution they have the Storage Block that's handling all of this. You can do offline/online and undo/redo quite easily.
I keep sending you example cause I'm a visual person :P, but look at that interactive article and let me know what you think: https://liveblocks.io/blog/how-to-build-undo-redo-in-a-multi...
Yeah - this is where I see us fitting well. It's not really the standard install/import and you're done issues that docs deal with. It's the niche problem <> niche expertise area where I believe we can excel - these tend to be very competent teams or developers who would be willing to take that hour and pay for it because the value is high enough.
I was using a few open source packages - TipTap, YJS, ProseMirror - but I had a particular use case that the docs simply didn't address (long story). It was the kind of help that would really require at least an hour sit-down with a very experienced developer to brainstorm with me on a solution, but there's not an obvious marketplace for that kind of touchpoint.
