I wrote CmdVees to scratch my own itch.
It works like a stack. You can copy several items in sequence (like any clipboard manager) but when you hit Cmd-v, the pasted item is removed from the stack. LIFO. It may sounds weird, I guess it depends on how your brain works. For me is very natural.
It can be configured to work like a queue, FIFO, for the other brain model.
Also, it splits entries in history by time, hiding older items in a submenu:
To be honest I don't use the menu more than once in a while.
It has other goodies like joining items or swap top of the stack with selection.
It's a commercial app but feel free to ask me for a license if you fall in love with the trial and you can't afford it.
2I've tried a few 3rd-party programs, but actually found none that clears its history based on time rather than based on some number of entries. I don't want my Mac to remember the last xx copy actions, but want it to remember the last xx minutes. (Or, even if the number of entries is limited: at least remove the history after some time.) – Arjan – 2009-08-02T12:26:26.867
3@Arjan - sounds like you should write that app. – Darren Newton – 2009-08-03T12:12:08.743
@Arjan or hire somebody on fiverr to do it.. used to be $5 might be a bit more now but not much – barlop – 2019-07-02T00:23:28.337
