This is a minor one, the pencil button on the far right of the url navigator should be presented as a button itself with outline when hovering instead of just an icon. The cursor doesn't change into a pointer to the button until its description is showed as seen in the video. I hope kde devs don't mind minor reports like this.
It's a fine bug report, and well spotted!
Indeed, good catch! Thanks.
Thank you you're very kind.
