In Eclipse and Notepad ++, I have text editors configured, so there is a translucent dot in the center, which makes it easy to count spaces. I prefer to use spaces instead of tabs in my text editing, and this feature is crucial when working with a space-sensitive language like Python.
I attached a screenshot with some kind of dummy code if my wording was not clear.
Anyway, is there a way to get closer to this functionality in Vim (or GVim)? I suppose there is a highlight , but that seems a bit sub. There's also good old-fashioned math, looking at the column number. What are my other options?
