I've noticed that Stephen Pope's "friendly-for-first-time-user" image 
uses the default morphic flaps, but sets all of them so that they do 
not pop open on mouseover.

I'm thinking that perhaps that's a better default generally.  I only 
find the pop-out-on-mouseover flap behavior to be friendly when I'm 
operating full-screen, which comparatively few people do.

For most flaps -- especially those that serve as "parts bins" (e.g. 
Supplies and Tools flaps), but also for flaps one hopes to use as 
"parking places" or to hold, say, a trash-can -- it (perhaps) makes 
sense to have them continue to open/close on *dragover* even if we 
remove the responsiveness to mouseover, in order to reduce the number 
of clicks required to complete the most commonly-needed functions, 
though there are rather evenly-balanced arguments on both sides here.

And, whatever else we do, probably the "Menu" flap -- if we retain it 
at all -- should only open up when proactively clicked on or dragged. 
Otherwise this can be startling (perhaps overwhelming is the better 
word) and it quickly gets annoying if it pops out a few times when 
you weren't planning for it to do so.

Or perhaps the Menu flap should not exist at all on the 
"first-time-user" screen?

I'm interested in hearing any opinions on these matters.

Of course, the various properties of any flap can be readily changed 
from the tab's halo menu, so that for the user who has started to 
feel comfortable in Squeak, configuring the flaps to be exactly the 
way one wants them is within easy reach.  But what point of departure 
should we give our first-time user?
