Setting default "Spaces" arrangement in El Capitan I like certain apps to have their own dedicated spaces, and I'm wondering how I can make it so those apps are automatically arranged in a specific order in Mission Control upon being opened. For example, here's an arrangement I have on my laptop screen:



Spotify on the left far left, and Mailbox on the far right.

I've used a tiling window managers on Arch Linux called i3, and this automated arranging was very easy to do. I don't expect the same level of customization on OS X, but if there was some way to retain my arrangement without having to manually move these spaces around every time, that would be fantastic.
The whole thing is much easier to manage if you don't use the system full-screen, which will always set a full-screen app to the right of any existing Spaces &amp; they cannot then be accessed by the standard  Ctrl ⌃   num  method

If you don't full-screen, then you can quickly lock any app to a Space by right-clicking in the Dock.

Also, make sure you don't have it set to rearrange Spaces automatically in System Prefs > Mission Control.
