I would vote to incorporate the features of the scheduler into the main sending window and do away with that as a separate plugin

I'm probably not going to do away with the separate plugin (or the
interface), just because there's a lot of stuff the plugin deals with,
that the regular, "Send a List Message" screen doesn't For the time
being, anyways If you look at the interfaces, they're pretty
different I agree that something a bit more unified for all the ways
to send a message and store a message should be the same thing, but
there is still the problem with how to get all the different ways to
do something integrated It's a lot of work, basically :) and I rarely
get paid to do any of it

What I could probably do is integrate some sort of hook for the
scheduled mailer in the, "Send a List Message" screen, if you do have
that plugin installed In the new alpha, I do this already with the,
"Edit Subscriber" screen If you have the log viewer installed, you'll
get a shiny new button that'll allow you to search through the logs
for just that subscriber It's handy

I could make a new form field group that automatically shows that says
something like, "Schedule for later" and gives a simplified interface
to schedule that message You'd still have to install the scheduled
mailer and set the cron, but those things are getting easier - I think
Beatitude now has a way to set the cron via a URL, so no editing the
source of the plugin, no figuring out absolute paths, and no
reconfigurating all this stuff when you upgrade The cron would look
something like:

GET http://example
com/cgi-bin/plugins/scheduled_mailings
pl?run=1

And even that URL is automatically made for you, in case you can't
figure it out I don't have it all polished up for Beatitude, but the
bounce handler in the new alpha is that way (I'll attached a screenshot)
