As of lately one thing in particular has really been annoying me, tab indention in Visual Studio 2005. I just hate it when I have hit tab to indent some line of code and then when I try to go back and delete the tab I have to now delete 4 spaces. I put a tab why am I now deleting spaces. So in my quest for IDE Utopia I had to find out how I could change this annoyance. Fortunately Visual Studio has always had many configurable options so I opened up the Options menu and found the Text Editor node. Then I opened up the Tabs node and there it was. Keep Tabs.

So to recap if you want to keep tabs and not spaces in Visual Studio just perform the following steps:
Tools > Options > Text Editor > All Languages > Tabs > Keep Tabs
