Is your feature request related to a problem? Please describe.
I like to keep my combuctor window narrow, and the Soul Shards tab runs off the side and bothers me. Also, I like to keep my UI as clean as possible, so having extra tabs at the bottom that I don't use is not ideal. Both of these are mild irritants.

Describe the solution you'd like
I'd like to be able to hide different bag type tabs at the bottom of the combuctor window. Either individually or a "Hide all bag type tabs" option. For example, since I'm not a Warlock or Hunter, I'd like to be able to hide the Soul Shards and Quiver tabs. Also, since I rarely use those tabs, I'd like to be able to hide them entirely.

I'm an idiot and after looking several times, I found this within minutes of submitting this issue. Nice job, developers. One step ahead of users!
