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).gwathdring supported this idea ·gwathdring commented
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.
