@poggie yea, that's the history of all your changes. We're planning to add an easy way to trim the history, but for now a workaround is to copy the content to a new pad and delete the current. Unfortunately that means other people will lose access.
In general we're careful about features involving deletion because we don't know what we're erasing. This one might take some time and a lot of testing.
@poggie its already in our plan, but I don't have a clear idea of when.
Unfortunately history isn't an extra feature you can turn off, it's an intrinsic part of how collaboration works in CryptPad.
My personal drive is up in the gigabytes, so I'd certainly like to be able to trim things. I'm planning to update our roadmap soon, so I'll think about where we could make this fit.
