It would be cool to export the lists, and even use it as template to import new games to the lists.
Also give us participating users more votes! I have only 3 left after posting some suggestions!
We plan to allow RSS feeds and export to CSV, hopefully with service integration (i.e. sync all my lists to Dropbox/OneDrive/Google Drive/etc).
It would be particularly nice to be able to upload from a CSV/list. I love your interface, but currently what's keeping me on Completionator instead was the ability to upload all of my games from all of my different services with about 30 minutes of copying, pasting and reg-exing. If KTOMG supported text file scanning to add things to my collection, it would take mere minute for me to switch over and I'd be quite happy to.
UserVoice does this to prevent people from voting on everything. So only the most important ideas are voted up.
You can redistribute your votes if you want. Otherwise, as we complete ideas, you'll get your votes back.
Thanks for participating!
