Use it constantly, as others have said windows -> type is the best way to use windows, and I do the same thing on my linux machines, actually a lot of the ones I use regularly are the same or similar in KDE (can’t recall if it’s out of the box or if I configured that)
CTL+windows+arrows to swap desktops (which have been in windows for a while now and I swear no one else uses), lots of ones around those are super useful. https://support.microsoft.com/en-us/windows/keyboard-shortcuts-in-windows-dcc61a57-8ff0-cffe-9796-cb9706c75eec for reference.
It could totally be setup to feel/work like a trackball, remember playing a bunch of warframe with mine and being able to “throw” it and have it stop when you touch the pad again, took getting used to but substantially more flexible than a regular analogue stick.
