For real. OP needs to give up on this ridiculous notion of tabbed whitespace and learn to use real, monospaced indentation. How wide is a tab? OP couldn't tell you because tabs are inherently dishonest -- a lie concocted by big keyboard to poison the unwashed programmer masses.
I meant for my personal projects. For the code that only I see, tabs are much better for navigation. But it's true that if there are several of us working on the project, the spaces are much better.
