I recently installed Ubuntu 17.10 on my laptop, and I'm irritated by the behavior regarding the Super + Number shortcut to open an application in the dash: The numbers on the icons in the dash are shown only after pressing a number. (Also, holding the Super key does not make the dash appear (I configured the dash to automatically hide when a window overlaps it). This isn't that big of a deal, as I can just release Super in order to display the application overview.)
I could, of course, try and remember which number was which app, or count through the icons, to figure out which number to press. Still, this is somewhat unsatisfying and I can't imagine that this behavior was intended this way.
Is there anything we can do about it?
