I recently updated KMail to 6.4.3 (25.04.3) and noticed now in the settings, there is suddenly an option to enable “Plasma Activities” – being a heavy user of Activities, I promptly turned that on.
But I cannot figure out what that does. Help very much appreciated.
A search through the user documentation shows nothing either.
I had no idea you could do this!
Ya. This would have been handy if I had known about it in the past, but I wasn’t using Kmail then.
Ah, that’s cool and I can see how this will be helpful for many.
What would make it more useful for me though would be to be able to do the same for mail folders, as I use mostly the same account/identity for all my e-mail on the same computer, but have dozens of folders that correspond to different hats of mine. I’d love to see that implemented
