Thanks a lot! This was the only thing I missed from the JS version, but it wasn't worth the slowdown/heaviness that that version brought with it. Now this gives me the best of both worlds.
Thanks. I just noticed a bug though: You can enter the search field by moving all the way to the top pressing arrow up or k. And then you can defocus the search field by pressing escape. This works now and I posted it on GreaseFork.
