MBButtons 1.1.0

So just a few things I'm noticing. Not always, but intermittently, the buttons will just disappear, and I'll have to reload the plugin.  Also, what are the button limits? It's scaling all the ones I create, but it's also limiting the lettering in the box. Lastly, when I try to add chat commands with a space in them, it negates the space and only adds the first part of any command, i.e.,/al toggle just registers /al without the toggle. Any help appreciated, thank you in advance!
