The pull event handler classes have a NAME parameter. I think a small, nice UI improvement would be to use the NAME parameter for the drop down list of pull handlers in the Settings UI:
I was looking at writing my own custom pull handler and wished I had control over the name that appeared there instead of it displaying the class name. (Not sure if you could also dynamically put the DESCRIPTION parameter of the selected handler either as a tooltip or neutral feedback div (like you do for the git version) as a hint, but that would be icing on the cake)
