Hi, I've been thinking about using slotlist.info as backend for our very own slotting tool for some time now.
To not lose features however, I'd need to be able to store some more attributes with the slotGroups – among others: radio frequency, tactical symbol, organisational level (company|platoon|squad), and parent-child-relations.
(For illustration, this is how it looks on our site)

Is this something you'd feel comfortable to accomodate or accept PRs? If necessary, I'd be happy to get a field where I can store a JSON blob or something :D
