Espresso is part of the default apps listed in QuickCursor, so it's not something you can delete from QC's preferences.
It used to be that you could go into the application bundle and edit the info.plist file, but that no longer works with the Mac Ap Store version I don't think.
Some options to work around:
1. If you're truly no longer using Espresso, you can delete its plist file (com.macrabbit.espresso.plist) from ~/Library/Preferences and maybe the app bundle as well. That might de-register itself in QuickCursor's list after relaunching QC. I'm not 100% certain but it's worth a shot.

Like no longer using Espresso. Can I take it out of the list somehow?
