Clipboard Manager Questions

I currently use iClip and it's been ok, but was considering switching to your clipboard manager since I am already using BTT for my mouse. Is there a way to auto convert to plain text things I copy to the clipboard? Does copying one thing after another keep all items on your clipboard without having to have it open? Thanks!

It currently doesn't auto convert but it has a button to paste as plaintext (or cmd+p)

Yes, it will also work while in background.
