foldlevelstart=1
add filetype 'git' to whitespace blacklist
ignore bundles
remove unused vim-git plugin and add tig like plugin -- extradite
make file finder behavior more like ctrlp
match filename instead of the whole path
remove neomru
skip vimfiler in unite buffer
add vimfiler ignore pattern
remap <C-R> to redraw vimfiler, in order to free <C-L> for window movement
intro unite-colorscheme for fast browsing
replace yankring with unite
remove unused plugin
replace ag/ack with unite source grep
delete blank line
hide line number by default
unmap rarely used 'close all mapping to speed up 'close current'
add fixed ZoomWin
