I've been having some thoughts about the sites and came up with a few features that might be interesting to implement.
Exclude re-prints from search results
Sometimes when you search you're just looking for the info from the parent album, so I was thinking that maybe you could add another checkbox in the filter box to the top right area. This could also be nice if you want to check how many albums you've got listed from one series of albums on VGMdb (for example Final Fantasy).
Improve the scan browser
I'm giving another shot on trying to improve the browser that is used when you've clicked on a scan. Since the suggestion I last made (
http://vgmdb.net/forums/showthread.php?t=3753) apparently seems to have been denied. All that really needs to be done is have the browser to stop at the location where the user last clicked on a scan. Having to browse 5-10 chapters to get to the next scan is just ridiculous. If this is not possible, then maybe "next" and "previous" buttons would do?
List of how many types of "x" you've got in your collection
How about adding a little list of how many doujins, promos etc. you've got in your collection?
Edit:
Total amount of tracks in the bottom of tracklists
Since we have total length of all the tracks, I figured it would be a nice idea to have a little text where it says how many tracks there are on the release in total.
