This works great in standard vim but in gui it doesn't, any ideas?

Maybe you would like to see '# hi i'm a first level header' or '## ....' etc. instead of the default fold label:

setlocal foldtext=Markdown_Foldtext()

function Markdown_Foldtext()
let l1 = getline(v:foldstart)
if l:l1[0] != '#'
return repeat('#', v:foldlevel) . ' ' . l:l1 . '...'
else
return l:l1 . '...'
fi
endfunction
