* use syntax highlighting for Guile attachments
http://localhost:1234/issue/36487#2

* enhance input with JS (to style known keywords)

* allow multiple processes to access db
Throw to key `sqlite-error' with args `(sqlite-prepare 5 "database is locked")'.

* Is it intentionally that there still is a http site? I would have
expected a redirect onto https.

* http[s]://issues.guix.info/ is also still alive. Shouldn't it redirect
to http[s]://issues.guix.gnu.org/?

* home page: present the newest issues first, and only open ones.

* Mumi has no paging: It only presents one page of issues, but it
doesn't say how many are there in total nor does it page through all
other pages of issues.

* Add links to all tag queries (such as "easy")

* add "mdate" (for message dates) and distinguish it from "date"
