per-filter current message

[jgross@mit.edu]

It would be nice if the current message could be cached on smartnarrowed filters (or something like that). For example, if I smartnarrow, and then move ahead many messages, it would be nice if the cursor returned to where it originally was when I go back.

       In my ancient barnowl (1.3), "smartnarrow -i" followed by scrolling through
       a thread to the bottom-ish, then "delete view ; expunge ; view --home"
       would place the cursor at the zgram immediately after the zgram
       it was on before I smartnarrowed.

       In 1.5.1, the cursor now ends up right (before? after? I dunno, I was
       smartnarrowed) the zgram I was on when I hit my "delete view; expunge;
       view --home" hotkey.  For a long (messagecount-wise and time-wise)
       conversation, this means that I now have a bunch of unread zgrams
       scrolled off the top of my screen that I have to page back up to.

       Was this an intentional change?  Is it the same in even newer barnowls?

       That sounds like it could be

       So the old behaviour that made more sense was actually a bug?

       It reads to me that the old behavior was believed to be not commonly
       known/used, and that the simplest way to fix an actual bug was to
       remove that behavior.

       Hrm.  That's kind of a drag.

       Well, now that we know there’s a use case, we could try to
       reimplement it correctly.  File a bug?

       Meanwhile, you can emulate the old behavior using the mark:
       recv:mark; delete view; expunge; view --home; recv:swapmark
       (Keybindings are C-SPC for recv:mark, C-x C-x for recv:swapmark.)

Replying to jgross@…:

For example, if I smartnarrow, and then move ahead many messages, it would be nice if the cursor returned to where it originally was when I go back.

rlink’s report was only about what happens when you delete and expunge the current view. BarnOwl has never done that when the view remains nonempty.

    I think I can simulate the old behaviour well enough with recv:mark and
    recv:swapmark.  Thank you.
