QS: make databases easily viewable / peekable to provide context on their contents

[mr-tz]

I really like the tags for strings which appear in different databases (e.g. #msvc, #winapi, but I find myself almost immediately wanting to open up and peek inside the databases when I see that. One reason why I feel like I want to do this is because there may be ambiguity in the tag name - for example, it's not clear what the tag #common is referring to, and I feel like I would get a better idea of what kinds of strings are considered "common" if I could look inside the database and see what else is classified under that tag.
