Hello developers, I don’t know where to write this, so here I am. I feel that having a pinning feature in Klipper will be good. Once a message is pinned, it stays on top of the clipboard list and never gets cleared until unpinned.
PS: The keyboard shortcut for editing the latest item in the clipboard has been removed from Klipper settings with Plasma 6 and it was a really good feature. It’d be good if they bring it back.
I’ve been waiting for this for YEARS! I know there was some discussion somewhere (I remember Nate chimed in as well), and I thought this was looking like it might be gaining some traction?! I mean, seems easy enough to implement. It could (and probably should be opt-in only. But yeah I wait for the day when this hopefully becomes a thing.
up.. It’s still missing 
yes it would be great.
also, I’d like to turn off the “invoke action” and “show qr code” buttons.
These sorts of things require someone with the time, ability, and interest to dive in and implement. One part of that can be a feature request through the KDE Bugtracking System, which was done a while ago: Bug 54212 Persistent/sticky/pinned/remembered items
The in-progress merge request mentioned at the end of that comment string looks like it is the first stage of enabling that feature in the interface, and has some pretty recent activity - I’m sure development assistance would be welcome

I implemented the feature here at feat: add star item feature for klipper (!5563) · Merge requests · Plasma / Plasma Workspace · GitLab and wanting to know your thoughts about it: Klipper Starred Feature UI Feedback
Thanks a lot, I’ve given the feedback.
