In reply to Krishna Thakur.

For right now, the UI is a little crowded. The team is working toward creating a better experience, but it may be a version or a few down the road before we see that. At the moment, the important thing is making sure the idea works, which is seems to do so well.

What I imagine we'll see soon is something like the block inserter for patterns or that patterns will be integrated into the existing block inserter UI. Currently, patterns are held in a sidebar, but that is temporary.
