[Alpine-info] feature request: new command "maybe"

[John A. Kunze]

I'd love to have a keystroke to invoke a command that does the following.
Not sure what to call it -- for now it's the "maybe" command.  It would

     1.  Mark a message with a new flag: "maybe"
     2.  Advance to the next message, similar in this regard to "delete"
     3.  Upon exiting, those messages are saved in a "maybe" folder

What I find is that there's a small amount of my constantly overflowing
inbox that (a) I know I need to save and (b) I know I can delete now.

But the vast majority of my inbox is stuff that I _might_ need, and that
I'd like to be able to dig out of one big bucket (not lots of little
folders managed by lots of rules) on an as-needed basis.  An important
property of this "maybe" bucket is that I can chop off stuff older than
a couple years without looking anything but the timestamp.

This would address a very important use case for me, which is that I
currently end up saving huge amounts of mail that is a mixture of
important things I knew I wanted to save and a very large amount of
things that turned out to be very unimportant, but I didn't know that
at the time of saving.

What I do know at the time of saving/flagging is whether thing is (a)
important, (b) trash, or (c) maybe.  Because it's a common use case for
me (anyone else?), it would be great to have single keystroke for it.
