How many custom, self-made tags can you have with org-mode? org-tag-alist seems maxed out at 26. Is that the limit? On a heading, I can C-c C-c and a (helm?) buffer comes up with my 26 tag choices. So can you only create as many tags as there are lower-case letters in the alphabet. Is this true? I would like to have potentially hundreds of tags as tags seem to be vaguely the same as a book index.
