I had an idea, why not adapt the well-known and appreciated filelight to graphicaly display useful collection stat info ? I joined a picture which should be self-explanatory

tell me what you think
mxcl, please tell me it\'s easy

the problem is that it would require an additional dependency which we really don\'t need.

as well, what would we show if the user did not have filelight?
