Looks to me like you can only select one file or one resource.

True, but this is easily doable by combining two Designer generated widgets and not more than five lines of code.
Hm.. Could you explain this? Right now I do it with only 4 lines of code, without using designer.

Hmm... This one you certainly can do within Designer, especially with the help of custom widgets.
In Designer, the central widget is a QWidget, which is the parent of my real main widget. This is all in Designer, but it's a bit of a waste to have a QWidget that doesn't really do anything.

Or I can use the setCentralWidget() function in the code. This costs extra lines of code to create the widget, set its properties and make it the central widget.

True, but it'd start to get difficult to use the tool.
True, but I don't think we're at that point yet. Right now, many more features could be added without sacrificing simplicity.
