macosmission-controlspaces
Is there a way to completely disable Spaces in El Capitan without turning off Mission Control, Dashboard, etc.?
If not, is there a way to disable drag to space?
I'm using Cinch and I find it quite annoying to be offered space switching when dragging the window to the top of the screen just to maximize it.
OS X 10.7.2 Update
Since OS X 10.7.2 Desktops (or Spaces) and full screen apps can be reordered, i.e. spaces can be mixed with full screen apps in any order a user may fancy, but with one exception - Dashboard and Desktop 1 (1st Space) cannot be moved.
Pre OS X 1.7.2 answer:
Based on several reviews and reports you cannot.
Seems like an oversight to me as I consider it as a must-have feature.
Be aware there's also something called automatic-ordering (System Preferences > Mission Control > Automatically rearrange Spaces), which apparently orders them based on usage.

I've found that if head to mission control and uncheck 'displays have different spaces', then logout/login you should be sweet. Worked for me anyways.
