Hi all,
I got fed up with the browser button row getting clipped so have developed an "OverflowRowMorph" that
provides a button to popup items that don't fit the current bounds. Not perfect but better than nothing!
 
The button disappears if there is sufficient space for all the submorphs.
 
I'll include in the last version of Polymorph when I get around to making a stable release.

Regards, Gary
