+
+* Improve bundle support in git to make it cheaper to host/clone
+ with dumb HTTP(S) servers.
+
+* Expose targeted reindexing of individual messages.
+ Sometimes an indexing bug only affects a handful of messages,
+ so it's not worth the trouble of doing a full reindex.
+
+* code repository integration (with cgit, gitweb, etc...)
+
+* migration path to v2 without breaking v1 "git fetch" cronjobs
+
+* imperfect scraper importers for obfuscated list archives
+ (e.g. obfuscated Mailman stuff, Google Groups, etc...)
+
+* consider using HTTP::Date instead of Date::Parse, since we need the
+ former is capable of parsing RFC822-ish dates, used by Plack, and
+ the latter is missing from OpenBSD and maybe other distros.
+
+* improve performance and avoid head-of-line blocking on slow storage
+
+* share "git cat-file --batch" processes across inboxes to avoid
+ bumping into /proc/sys/fs/pipe-user-pages-* limits
+
+* make "git cat-file --batch" detect unlinked packfiles so we don't
+ have to restart processes (very long-term)
+
+* support searching based on `git-patch-id --stable` to improve
+ bidirectional mapping of commits <=> emails
+
+* linter to check validity of config file
+
+* linter option and WWW endpoint to graph relationships and flows
+ between inboxes, addresses maildirs, coderepos, etc...
+
+* pygments support - via Python script similar to `git cat-file --batch'
+ to avoid startup penalty. pygments.rb (Ruby) can be inspiration, too.
+
+* highlighting + linkification for "git format-patch --interdiff" output
+
+* highlighting + linkification for "git format-patch --range-diff" output
+ (requires mirroring of git repos)
+
+* parse and allow (semi)automatic-mirroring of "git request-pull" output
+ for coderepos
+
+* configurable diff output for solver-generated blobs
+
+* fix search for messages with multiple Subject:/To:/From:/Date:
+ headers (some wacky examples out there...)
