Would there be a way to resize the input/output fields?

Current layout only accepts 3 lines which is not sufficient when formatting SQL or JSON.

Good catch! I will check into that. I’m sure there are other tools with some quirks too. I will be going over them all to make sure issues like this are taken care of, Thanks!

You can add "resize: vertical" to your div style and that's it, users can resize through a small lines icon on the right bottom.

Thanks, yes other pages use the resize, I missed that one (likely more), I’ll be checking all the tools over this weekend!
