Ability to edit or delete "Wall" or "Channel" names from widget drop-down list#2576

In the new Wall/Forum widgets, Discussion widgets and Comment area widgets - we need the ability to delete and edit created “wall names” or “channel names” from the drop-down list. As people get started, or are testing, they will potentially be creating many new channels or walls that they will not actually use. (or will not realize they don’t have to use the “default-xodsaf” names that are auto-populated.) This potentially leads to a LONG list of wall/channel names in the drop-down list, cluttering things up and making it hard to manage.

Would like the ability to delete out or edit/change the name of wall/channles after first created.

Thank you!
