QIde, a new IDE for Qt4

[high_flyer]

No, subdirs are well supported. The problem I think is a sub-project name identical to the main project name. No? If it is that I work there.

No the name is not identical.
I just tried it under linux, there it works fine.
I guess this has to do with the fact its under windows.
Maybe an issue withe the way the path notation is handeled under windows?

external libs, lib paths and external include paths can be added in options dialog by create a new variable in variables tab.

I know, I also said that in my comments.
But when I have 10 various lib locations, and include locations, and I need to add manually INCLUDEPATH += and the libs path in the pro config line, then the pro config dialog prety much misses its use (in my oppinion).
But the problem is that the config dialog is messing up the pro file - see attached.
In the attached pro file I added INCLUDEPATH = /some/path/to/test.
See how it was saved.

Opening a project file on text editor is not the solution, QIde must understand and create all project files.

Agreed, but as long as its not the situation (i.e configuration through QIde is not working well) it should be possible to edit the pro file directly, as a file in QIde.
