Is your feature request related to a problem? Please describe.
This isn't really a problem per say, but I don't need to have the main quest tracker header showing the label "Quests" all the time (not ever, really).

Describe the solution you'd like
It would be nice to be able to disable rendering of the block header on a per-block basis. I don't need to see the Quests block header ever, but I might still like to see the Achievements block header text when I'm tracking one, for example.

Describe alternatives you've considered
I did try to make the Quests block header fully transparent, and although I was able to make the background transparent, the text color doesn't have an alpha slider, so I couldn't get it to go away.

However, it would still be better to be able to disable the header entirely, and have it collapse that space down for more content area.

In the next version, you'll be able to disable the header and changing its height.
