I don't have found this request on the list, but maybe I missed it as there are so many ! :)
As we have : Edit > Show all entries, Show all expired entries.
It could be nice to have Hide/Unhide expired entries.
Here is my user experience:
I am used to not delete the expired entries before +-2 years after the expiration date.
I like to keep expired entries because sometime clients requests me to re-open a previous (very old) login/password. In this case I am really happy to find it back easily with keepass. But this kind of requests happens rarely. Most of the time I don't need to see the expired entries.
So, to keep an easy & quick visual reading of the entries; it will be awesome if we can just "hide the expired entries" and simply uncheck this option when we need to see them.
Thanks again for all you work on Keepass!
