Check for Updates too much selected - I only want to update installed stuff

The check for updates feature checks off everything that is newer than what is installed or checks it off if it is not installed.

I don't need to install a ton of languages, just update what I am using.

It needs to have select/deselect all options, it should probably only show items that are updated. Ideally, it should show items that have updates or are not installed or are new, it should only check items that are currently installed, it should have select all, clear all buttons or rc menu option (prefer both).

See how StarDock does their update system...
