Is it possible to have a buffer showing the headers of a file in a
buffer in a popup window to the left of the main window in org-mode
please?
We already have 'neotree' but that just shows the files in a directory.
What I'm looking for is something like 'Imenu' but in a popup buffer,
which is activated in something like 'M-F8' and displays, and then when
'M-F8' is used again it closes the popup.
Ideally, this could be used for any buffer that is being used, whether
its latex, mediawiki, or whatever, although possibly not for gnus.
