I'm kinda new to cmp so i apologise if this has already been asked (coulnt figure out how to work the search thing here.....when i clicked search, there was no box put put in my query :/)
anywayz, i was thinking maybe you could support a url in the dat files to make updating easier. So if the dat file comes with a url inside it, if we press an update button it will automatically go to that url, and check if there is a new version of the dat and dl it (assuming it exists)

thanks for the awesome tool and keep up the good work :D
