I would like to see included in search options, age in days. Very useful when used in a search folder, showing emails from the last week.
How is this still not a thing? I chose Thunderbird over eM Client when evaluating various options a couple years ago, and the lack of relative dates in search folders is what made the difference. The folder I use most in Thunderbird (on my Windows computer) and in the Mail app (on my Macs) is “Last 7 Days.” I have lots of filters moving messages into various folders automatically, so to have a search folder that aggregates these into a single location is critical. I installed eM Client again today to give it another chance but nope, still no way to get a rolling search folder. Stunning, really.
