Keep markdown headings open when switching buffers?

[wolfv]

I use markdown files with #headings, a vim plug-in folds and unfolds the headings.

When I initially open a markdown file in vim, all the headings are folded.
I drill down through the headings to access a line.

I switch to another buffer, read a line, and then switch back to the previous buffer.

All the markdown headings are refolded :(
I have to drill down through the headings again to access the line I had unfolded.

Sometimes I need to reopen 2 or 3 headings.
Is there a way to keep the markdown headings open when switching buffers?
Or do you know of a markdown plugin with this desirable behavior?

Thank you.

Vim should not automatically close fold unless instructed to by
'foldclose' option. Plugin may also though alter Vim behaviour, but I
think it is unlikely this is the case.

Also check out 'foldopen' option.

Thanks Nikolay Pavlov,

What you say agrees with the Vim manual:

help: fold-behavior > For manual folding the defined folds are restored.

help: fold-foldlevel > No manually opened folds will be closed.

I am not using the 'foldclose' option, and 'foldopen' option is not what I need.

The only thing in my vimrc file is for folding:

autocmd FileType markdown source /home/wolfv/vimfiles/ftplugin/markdown.vim

Is markdown.vim part of the default vim install?

markdown.vim and my small .vimrc file are attached.

The only purpose of my small .vimrc file is folding.
It sources the markdown.vim file, which was copied from https://gist.github.com/vim-voom/1035030

[wolfv]

The problem was solved by removing line 32 of https://gist.github.com/vim-voom/1035030

setl foldlevel=0

Now vim preserves folded state when switching buffers.

Thank you for your patients.
