Thanks! I’m not sure which seems better either.

If a user prefers to use git annex assistant or preferred content that shouldn’t
interfere with this. But to my mind, opening an attachment is a pretty clear
indication of the user’s desire to fetch the file from git annex, so it would be
nice to do it.

Well, I think it would have been nice, but the “preferred content” feature you
reference below seems like it could cover most of this. And, while I think that
trying to open an attachment is a pretty clear indication that the user wants to
fetch the file from git annex, exporting is much less clear. I’m pretty
convinced that Kyle is right that git annex support belongs in org-attach, but
not elsewhere.

I’m not certain how preferred content works, but it doesn’t seem to apply to
which content is added to git annex (as opposed to added to the git repo
itself), which is what org-attach-git-annex-cutoff does.

Thanks! I’m going to use Kyle’s suggestion here, to use =git annex find PATH=.

best, Erik
