1. How is your find all references different than the show dependencies function?
2. Your quick info function looks similar to just hitting Shift-F1 when highlighting an object. Yours maybe doesn't even do as much. Are you aware of the Shift F1 command?
Quick Info might potentially involve to show more information (definition, references etc). If not, and if nobody sees value in it, I might take it out.
After installing your product it has been sitting for several minutes grabbing all the schema or something... so I can't get even get quick info to work at this point when Alt-F1 works every time.
But very few people even know about hitting Alt-F1. Might make sense for your quick info just to call that same function so people even know how to do it.
