Better than the comments here made it sound

A lot of people complain about change. I like the new design. I agree with everyone who said it's not obvious that "JSON Encoder" and "JSON Decoder" are separate "tabs" and I couldn't immediately figure out how to paste my RSA keys instead of a symmetric key. Otherwise, I think it looks pretty good. I like the new typography and I find the more muted colors easier to take in.

Just wanted to drop a note with a little praise in case the only people speaking up are the unhappy ones. I appreciate that someone is maintaining this tool. Thank you.
