Channel Editor -- Feature Request?

[BigKahuna]

Providers these days love channels.   Deleting Groups and Channels is painfully slow when you have 35K+.  It would be nice to have a list of groups that you can deselect all and tick off the ones you want to keep.  Then, click and let run overnight.

That's what it does at import time. Use the filter channel groups box, unselect 'all groups' then tick only the groups you want to keep before hitting 'save'
