recent maint, have not tried in -Q.
summary: point moves and zoom level reverts when refreshing agenda
1]
i find that,
when i do an agenda agenda [daily/weekly] and i have point on a task,
and i go do something in the task and nearby nodes, and a bunch of
other things, and return to the agenda,
and refresh agenda view [and also just in case any of the markers god
out of date and could cause corruption if i operated on a task from
the agenda],
that point moves from the task. i wonder if it makes sense to try to
keep point on the task that it was on?
2] i also find that refreshing resets the zoom level created using
text-scale-increase. i wonder if this can also be preserved. to me,
refreshing refers to updating the contents of the agenda view, not
things like text scale.
thanks.

I also find the point movement erratic sometimes in the agenda. IIUC
the line number gets stored for the agenda and after agenda-redo point
is set to that line number again.
I also thought a bit about a better behavior. One could implement a
heuristic which trys to place point at a line which looks "very much"
like the line which contained point before the redo. But I'm not sure
how crazy that is.

This is a wanted feature AFAICT. I think the following patch is a
reliable way to achieve the preservation of text-scale for agenda-redo.
Ciao,
Marco

The following is an alternative patch which I think is preferable. It
just keeps the needed local variables for the text-scale (aka zoom) in
good order in function org-agenda-mode.
Further I use this patch already for some days and could not find any
issue.

Marco

* lisp/org-agenda.el (org-agenda-mode): Save and restore local

thank you! do you think this patch could be integrated into core?

Yes, I think so.
Hopefully Nicolas and Bastien see it the same way.
BTW meanwhile you could overwrite function org-agenda-mode with the
patched version residing in your init file.

Thank you. It looks good. Feel free to apply it.
I have two suggestions however:
1. There is some code duplication, e.g., (dolist ...), could this be
factored out before applying the patch?
2. Would it make sense to add the variables to preserve in a dedicated
top-level variable instead of burying them in the code?
Regards,

Yes, done, thanks for the hint. The patch has been committed.

I don't know. Possibly this is a YAGNI. A top-level variable could be
introduced any time. Further someone might come up with a freshly
rewritten agenda in the meantime. ;)
BTW: It might be a good idea to take ideas from `list-buffers' and
friends for the rewrite of the agenda.
Ciao,
Marco
