@xot I still have a strong (but sad) reason to use something else: CryptPad is extremely inaccessible.
I'm not talking about a level of inaccessibility where I could go file a few issues and they could fix them. Rather, it's demonstrably unusable with keyboard only, screen readers, and other accessibility tech. 0 out of 10, if you sent me a document I couldn't read it sort of accessibility.
Worth keeping in mind if you're not just using it for yourself, and you want a diverse audience of readers and collaborators.
