I think I've finally settled on this as the interface for my #SoloRPG toolkit.
It's got its own website now, which is nice. Should work in all browsers, needs JavaScript enabled (because, I mean, do you want to send a web request every time you need to roll a die?)
Obviously you could use this for "non-solo" #TTRPG as well, but it sort of came out of my need for something compact that I can have on my phone or laptop while I'm out and about and doing #journalinggame s
