Completion UI considerations

[SebastianSzturo]

Thanks for starting this project, really appreciate someone trying to port the LSP plugin from vim. (I did try a year ago and gave up! :P)

One thing I ran into while exploring this last year, is that Nova doesn't really have the same UI concepts as VSCode. The reason why VSCode's completion are so seamless are due to them being rendered as translucent comments that is easily readable and dismissable:

For Nova we really only have the Language Completion concept that might not be ideal for longer codeblocks:

Have you put any thought into this? I guess for now Language Completions is better than nothing and maybe we can get the attention from Panic to do something about this.
