permanently disable "Add to clippings" shortcut
 

When OmniOutliner's "Add to clippings" service hijacked the Cmd-Shift-., Google brought [URL="http://www.manytricks.com/servicescrubber/"]Service Scrubber[/URL] to my attention. However, it seems that OmniOutliner periodically re-hijacks the shortcut, which I use all the time in Emacs. Is there some way to prevent it from doing this?

ServiceScrubber edits the Info.plist of the applications, and though I don't know the details, it seems to me that this is how it pulls off its feat. I believe that is why the customizations are usually undone when you upgrade an application such as OmniOutliner. I find I have to make the changes using ServiceScrubber again and again, seemingly whenever I update an application, presumably for this reason.

A solution would be a mechanism that watches the plist files that you've customized for changes (as is very easily implemented using launchd), and confirms whenever they are overwritten that you want to restore your customizations to the service menu. Perhaps implement this or suggest it to the developer of ServiceScrubber (while making a donation...)
