Have you looked at the AutoSlim package?

Have you tried the MinimalFortran package yet?

I just looked it up on the excellent page provided by the awesome wbond

and it appears in my list of available packages through PackageControl (also provided by wbond whose place in the pantheon of the great is assured)

Go to this file:

Packages/User/Base File.sublime-settings 

Add this line:

"rulers": [0, 4, 8, 12, 16]

Do you see the lines that have appeared are at every 4th character?
If your tab setting is 4 now you have your tab marks.

Change the settings above to match your preferences.

Locate this file:


Make a copy of the current file as a back up. (Always give yourself the chance to easily roll back changes in case your changes are not as good as you hoped.)

Now open the file in your favourite image editor and change the colour as you feel is best. As you save the changes to the file you should see the change in Sublime Text 2. If not then close and restart ST2 to see the changes.
