Hi!

Maybe I'm missing something very obvious, but how can I resize widgets in panels?

E.g. when I drag a notes plasmoid on the panel, it looks like this, and I can find no obvious way to change its size:

It does change to a normal size after relogin (like this), but still not resizeable.

You could resize when the 'Alt' key and the mouse right button are pressed.
