I'm coming from using Komodo IDE, where all the spaces were displayed as dots, but up in the middle of the vertical area above where a period would be. They would be at the same height as would be a dash (-), but a dot (.) rather than a line. I thought I saw Sublime Text doing this at one point, but its not anymore & I don't see where to set it to _always_ do this for me.
How can I set this behavior?
