Give CopyQ a try. Open source, cross platform clipboard manager with tons of features.

One example option is being able to only ever paste plain text. It also has lots of programming hooks, I have a few for doing things like converting a line-feed delimited list into one delimited by commas and quoting the values.

Does anyone know how to remove the lock screen temperature display?

edit: figured it out, I needed to disable weawow’s always-on notification. I thought that I had done that right away after installing but must not have hit save or something.
