I have configured Tab as Omnicompetion in VIM 7.3:
inoremap <Tab> <C-n>
This is convenient, but I would really like to have regular tab back at the beginning of a line! Is there any way to check if the preceding character is whitespace or a line beginning, and if so to insert a Tab character rather than omnicomplete?
Thanks!

I have been using this for some time now:
This lets you use the tab key normally when the cursor is at the beginning of a line or not on a word, otherwise it executes the control-p completion key—you may change it to <c-n> for your use, although I find <c-p> more useful.
[Although I have modified it, the original idea for this probably came from the Vim Users' mailing list, but I did not keep any notes about where I got it.]
