How can I hide brush until a user actually tries to select a region? #263

Currently it looks like it is a requirement to define a region in order to get the brush to work. My use case is that I want to allow a user to select a region on a chr but I don't want to have to pre define the brush location. Is this possible?

Found the solution. I can add brush at chr1:1-2 and the brush will not show but it will allow selection.
