We need the ability to change the imp to a cursor
You can only grab with the imp. Although you can make a sculpt follow the imp and make it look like a cursor, you can no longer grab objects with it, which makes this functionality pretty useless. We should be able to create our own "imps" that look like cursor arrows, character helpers that are not imps etc..
There's still a lot you can do with the follow-imp setup that doesn't involve grabbing things with the imp. But I take your general point.
I think this kind of functionality will be coming with the VR update; things like that have been hinted.
