Continuation of bug #451187 Copy a value upon double-click (or single click) on it
This looks even more hidden than current "Ctrl + C" approach. Be it me I would add a context menu.
I think that a context menu is fine too. I just saw that copy upon click with IPFS Desktop, so I figured I'd ask here for the same.
A possibly relevant merge request was started @ https://invent.kde.org/network/falkon/-/merge_requests/30
Relevant functionality was added in "Version 22.08.0".
