With 3 monitors now, virtual desktops seemed a little less nice for providing a context for different projects/activities. So I started looking into KDE Activities. They are a lot like virtual desktops, but seem a little cleaner. One neat thing is you can select which Activities you want an app to show up in. This allows me to show email in my HM default activity but hide when I’m working on projects to minimize distraction. If I need email for a bit in an activity, I can also enable it for that activity.
KDE has a lot of customizations for activities – one example is the menu favorites can be changed per activity.
