hey there,
I wrote a bit of code that allows me to have the tags always at the
utmost right position in the file... I often have windows that are
bigger than the standard 80 characters wide default and I dislike seeing
the tags in the middle of the window.
I started doing this and found out that adjusting the tags every time I
resize a window breaks tracking org-mode files with git. If the last
window is just a bit smaller than last time, the complete line will be
shown as a diff. Therefor hooks are used to reset the column variable to
1 so that git tracking still works.
If anyone wants to use this or want to look over it if I could do this
smarter, I'm very happy.
If the response is positive I'll clean it up a bit and maybe it is worth
a contribution or a worg page. :-)
best regards,
benny

Maybe a safer solution would be to use an overlay for displaying tags.
This way you don't need to worry that changes in the tag display will
be seen as a diff. But maybe there are already too many overlays on
an Org page...

I tried it. Just replace defcustom by setq, because the defcustom
definition is wrong here.
It works very well for small files, but the hooks are slowing down Emacs
display for big files (i.e. the 400k Org file in which I spend my daily
life.) Perhaps using overlays would also fix this...

Definitely worth a new "Org hacks" entry!

Just send me your username on repo.or.cz.
Thanks!
