;; Todo, minor things:
;;
-;; o Support escape characters in `message-tokenize-header'
-;; o Split-fancy.
-;; o Support NOV nnmail-extra-headers.
+;; o Don't require half of Gnus -- backends should be standalone
;; o Verify that we don't use IMAP4rev1 specific things (RFC2060 App B)
;; o Dont uid fetch 1,* in nnimap-retrive-groups (slow)
;; o Split up big fetches (1,* header especially) in smaller chunks
;; o What do I do with gnus-newsgroup-*?
;; o Tell Gnus about new groups (how can we tell?)
-;; o Respooling (fix Gnus?) (unnecessery?)
+;; o Respooling (fix Gnus?) (unnecessary?)
;; o Add support for the following: (if applicable)
;; request-list-newsgroups, request-regenerate
;; list-active-group,
;; o IMAP2BIS compatibility? (RFC2061)
;; o ACAP stuff (perhaps a different project, would be nice to ACAPify
;; .newsrc.eld)
-;; o What about Gnus's article editing, can we support it?
+;; o What about Gnus's article editing, can we support it? NO!
;; o Use \Draft to support the draft group??
+;; o Duplicate suppression
+;; o Rewrite UID SEARCH UID X as UID FETCH X (UID) for those with slow servers
