First thanks for this excellent plugin - nice job.

I have a minor suggestion that I think would work quite nicely for handling large numbers of jobs with boolean options.

For booleans it would be nice to have a select/clear all items in a view. We have a large number of jobs and often need to disable a group at a time. For example when we go into a release phase we enable a bunch of jobs that don't typically run. Being able to enable/disable all of these jobs in one go would be very useful.

Thanks
Andy
