[FR]: Optimize UI for modifying command alias

[hustrjh]

Is your feature request related to a problem? Please describe.

It's not convenient for users to modify command alias. For example I haven't found the method to rename alias without adding the same command.

Also selecting existed commands is not convenient as users can't input and filter.

Describe the solution you'd like

Maybe you can imitate the way what chorded hotkeys plugin does. It is easy to select commands, modify, rename alias, sort and so on.

I hope this will make command alias better.
