[Qt-creator] Folding mode

[Guido Seifert]

Hi,
I think Qt-Creator isn't bad, but currently no competition for KDevelop.
What do I miss most? A usable folding mode. I'd like do set my own folding
markers like in KDevelop. I could not care less for the markers within a method, 
if one needs those, the method is too long anyways. But also the fold lines, 
which open/close the whole method are ugly when a header has more than one 
line. And I'd prefer to have the method's comments within the folded area, too.
