Do you like those little notification pop-ups that Mylyn and RSSOwl do? Do you like Pop-up Video?
If so, please voice your support on this enhancement request against the Eclipse Workbench to include support for a standard desktop notification pop-up.
I think this is a great idea as I’ve seen a lot of questions on how to do those “Mylyn pop-ups.” Plus, the ability to notify users in a fairly discrete manner is nice.
