Thank you Nyall, I understand. The reason I needed to resize the window was to better fit some image content in my HTML help.
Taking the opportunity, I'm a C++ and Python developer and I would love to contribute on the project. Is there any need for help in the Processing Framework (since I'm already a bit familiar with it) or in others areas? I would probably need some guidance at first but I've been using QGIS and developing plugins for some time now, so I guess it wouldn't be too big a learning curve.
