I did not mean to imply that you could not run your other stuff in addition to GIO. I am okay with keeping (and adding to) everything you have now. This is merely to improve what Zeitgeist can know. Things this patch can provide you with: - The name of the application the user launched (localized if desired) - How to launch it - What it was launched with - What mime types it supports - A description of the application (localized if desired) - The name of the binary that was launched - The flags the application was launched with Probably more... > > I think using GIO andd application plugins together could be a > solution, Especially because GIO will allow us to even know when a > user launched an app. This we dont have now.
