While I think these are very useful, especially for new users, they can make the reltype selector very long and might be overkill for more experienced users. Ideally we'd have a way to toggle help off (have it on by default) that said users could configure, like we have in the prod rel editor to show/hide descriptions and whatnot.

 

Edit: In fact, the "help" button is still there, but the description is still shown inline too. I'd argue it should only be in one of the two places
