Description
So far I could only find an option to keep a certain number of items. I suggest a feature where Pano either a) keeps all items younger than $time or b) keeps items younger than $time and up to the history length.
Why?
Many people don't actively keep track of what in their clipboard manager history, after all, they exist to manage the history for you. So it is easy to copy something important like the number of a banking account, URL or picture, because you are in a hurry, and then leave the computer. You might forget or did not notice what you put it in your history. Then after some time you log in and are surprised what sensitive information is stored on your disk, maybe with somebody else being present (co-worker, friends, etc.)
So adding a function that deletes entries that are older than X minutes, hours, or days would come in handy.
