Major Description
I've bumped into "describe pretty" feature...which was probably a usefull thing when it was introduced....but I haven't seen it documented anywhere ... google results are only about the implementation of the feature.
there are qtest about it:

this feature makes it possible to render column comments more nicely...
I think beeline is already able to address formatting issues like this at a much wider scale; so it might be ok to remove the 'describe pretty' support...or at least I think it would be better to put efforts into displaying things on beeline more nicely
