I thought it might be possible to get a bit closer to what you want if 
QScintilla had a "foldChildren" method, so I wrote one. You could use this to 
add a "Toggle Child Folds" and "Collapse Child Folds" to eric3's View Menu. 
If you also created keyboard shortcuts for these new menu items, it might 
make quite a nice improvement to the user interface.

This function should be added to eric3's QScintilla.Editor class:

def foldChildren(self, line, toggle=True):
	if toggle:
		btnstate = QextScintilla.SCMOD_CTRL
	else:
		btnstate = QextScintilla.SCMOD_SHIFT
	linepos = self.SendScintilla(
				QextScintilla.SCI_POSITIONFROMLINE, line, 0)
	self.emit(
		SIGNAL('SCN_MARGINCLICK(int,int,int)'),
		(linepos, btnstate, 2))

(A ctrl+click toggles all the child-folds of a foldable line.
 A shift+click expands all the child-folds of a foldable line).
