Of course!

A few things: if you're adding several messages at once, you can "bulk
associate": use Gnus' process mark ("#") to mark all the relevant
messages (or "T #" for a whole thread), and then
`gnorb-gnus-incoming-do-todo'. I don't think this will work until you
_already_ have an Org heading in place -- if you mark a bunch of
messages and use `org-capture', I'm not sure it will do the right thing.
It should, though -- I'll see if I can add that.

The "&" might not be showing up simply because the gnorb function
doesn't re-draw the Gnus summary buffer. I've found that mildly annoying
in the past, I'll try to add that, too.

This is something I wanted right from the beginning (to annotate
individual messages), but have never come up with a good UI for it.

Are you using a log drawer on the Org heading? That's my preferred
method of tracking TODO progress. What I could do is, when you choose
the "add a note" action (or the TODO state change prompts for a state
change log note), automatically insert the message id of the relevant
message into the log note text.

Alternately, if you wanted to keep the Gnorb notes separate, add the
note to the registry entry.

But then what? The only two ideas I can come up with are:

Provide a `tabulated-list-mode' buffer showing correspondences between
message headers and notes. But it seems a bit goofy to provide a whole
new view just for this information.

Provide a command that can be called on a message to see the relevant
note. There could then be three different marks: "¡" for relevance, "&"
for association, and "@" (or something) for association with note.

Any ideas?

Avoiding the need to tick messages was one of the points of Gnorb! But I
see what you mean -- active Org projects are not automatically
visible...

Hmm, ideal behavior would be that all messages associated with TODOs not
in a "DONE" state would always be visible. That would be nice!

I don't think Gnus allows for this behavior by default, but what I could
do is provide a `gnus-summary-limit-to-gnorb-undone' command, bound to
"/ g". You'd enter the group, hit that key, and it would display all
currently-active tracked messages. That's not a bad idea. I'd still like
to make it do that by default, though.

"A T" ought to fetch old messages too, I use that all the time...
Threading in Gnus is arcane magic. You can almost always get it to do
exactly what you want, but it might take research and experimentation.

This is a dumb artifact of how Gnus currently works, and this
requirement will go away if we can ever get the feature/gnus-select
branch to land. The backend is currently necessary so that nnir uses the
correct Gnorb function to retrieve the messages. Have you added a
"nngnorb" server to your `gnus-secondary-select-methods'? I'm not sure
why simply entering the server buffer would do anything.

Hmm, did you add the nngnorb server via "a" in the server buffer? I've
never tried doing that, probably safer to add it to
`gnus-secondary-select-methods'.

Not with Gnorb tools. "A T" is probably all you've got, but try playing
with `gnus-refer-thread-use-nnir' and surrounding code?

No one is!
