Vim folding - mark opened folds -

-

is there way see, opened folds in current file? have problem when opening folds , moving around, i'm not able find line fold started from! maybe there option set nice-looking folding-hint next numbers. maybe this:

+ 1 void myfunc(void) { | 2     printf("hello world\n"); | 3     printf("goodby world!\n"); - 4 }   5   6 void anotherfunc(void) ...

it nice! used google , used vim-help found no way this.

kind regards, musicmatze

try :set foldcolumn=1

if want more fold columns indicators increase number, example below uses :se fdc=3 (the shortcut)
