Regarding spacial awareness, because I have the same window in a given "desktop" all the time, my spacial awareness is locational. If I'm in my IDE, I know it's 2 desktops to the right to get to my terminals. From there, 3 to the left to get to my company chat. Etc.
It's even better in ubuntu because desktop switching isn't just left/right, it's up down. So I can really think geographically. I guess that's just the kind of brain I have - for example, if I want to look for tickets for a movie I want to see, I search "movie theater" in google maps and click the theater in the location I want to go to, then navigate through ticket buying etc. shrug who knows man
Also, it's nice for spacial awareness. I feel a little bit lost when a window takes over the entire screen and blanks everything else out.
