[Feature] Command Palette(CMD K) + Keyboard shortcuts

Here are a few open source options:
https://cmdk.paco.me/
https://github.com/timc1/kbar
https://github.com/harshhhdev/kmenu

A few commands that I'd like to have
- new chat
- previous/next convo/search convos

A lot of the buttons that expand/collapse can be hidden away this way.
They are quite cluttering and not frequently used for most users I'd imagine.
