As the title said, I customized my system according to what I liked. It's probably a mess of features and design elements cobbled together from the OS's I've used (or would like to use).
There's also some features I've customized that is hard to show via screenshots, like mouse gestures to move windows around different screens and virtual desktops.
I don't think I've achieved everything I want here, but it has gone way further than I've imagined it'd go.
Now you just need things to put on the calendar.
I actually am trying to get it hooked to my google calendar. That widget used to support that feature and have it work. However, recent changes have borked that functionality, and I can't seem to find another widget that does the same.
Or I can just move away from google calendar.
Google bad.
I'm weaning myself away from it. However, it's still unavoidable in my case because my work uses it. Thus, my work-related appointments and such are on there, which is one of the reasons why I had that widget in the first place (to monitor work-related appointments, deadlines, etc).
