The difference of Pharo (and it's UI!) was what lured me into it, not what
constituted a barrier :) And while i would also make a case for difference
only for it's own sake, i think there are very good reasons for the pop-up
menus.

They are very good reasons for popup menus.

The work menu is not one of them

Popup menus should (mainly) be used to propose contextual options.

Now take a random menu in Pharo, and look for the items

that applies only in the current context.

That�s also the reason why the menu are far too long.
