Ok, I'm very happy with the fact that now all of my screens have menu bars at the top (this is very handy). However, what I'm not pleased about is how every monitor has its own set of Spaces, and that you can't seem to have the old Spaces configuration (i.e. Lion, Mountain Lion) without giving up the menu bars on both screens. I use my laptop with an external screen, positioned above the laptop and I've now found spaces unusable with Mavericks as it doesn't fit with my workflow. On Mountain Lion, I used the following: - Main space (usually whatever I'm working in Terminal or MATLAB, sometimes with some documentation in the browser). - Communication space (IRC, Messages, Skype, Mail) - Organisation space (Calendar, Wunderlist) - Audio (iTunes, Spotify, Downcast) - Spare Space (whatever else, sometimes I'd send the browser here if I didn't need to view documentation whilst I work). In each of these, I'd spread the windows across both screens (organized with Moom) to suit myself, but on Mavericks I can't do this unless I relinquish having menu bars available on both screens (something which I find invaluable). I'm wanting to upgrade my work-issued Macbook Pro to Mavericks (currently on ML) but I'm reluctant as I'll lose these abilities unless I can find a way to retrain myself. So, my question is, how do others use Spaces on multiple monitors?
