I noticed the tag alignment produces inconsistent results in org-indent-mode. If you type in the header, the normal (non-indent-mode) indentation is used, and the tags do not appear aligned. If you add tags or type "C-c C-c" the tags are aligned correctly.
Here's an example file: --8<---------------cut here---------------start------------->8--- * Heading :tag: ** Subheading :tag: --8<---------------cut here---------------end--------------->8--- Here's what happens before and after typing in the heading: http://imgur.com/a/Ljpw2 I'm using: Org-mode version 7.7 (release_7.7.201.gcd8d) GNU Emacs 23.2.1 Great work on org-ident-mode by the way! I've noticed a bunch of recent improvements. Regards, Jason
