Exactly! Pls, add possibility to set options listed below:

(from my vimrc)

set tabstop=4     " a hard TAB displays as 4 spaces 
set shiftwidth=4  " when indenting with '>', use 4 spaces width
set expandtab     " On pressing tab, insert spaces
set softtabstop=4 " insert/del 4 spaces when hitting a TAB/BACKSPACE
set shiftround    " round indent to multiple of 'shiftwidth'

.
