Here what I did:
- added support to sort the content of QTable objects of the info dialog (bug #1616485) 
- fixed tabstop order for some widgets 
- reduce the really annoying flickering of the LCD widget in the main window, by use QWidget::setPaletteBackgroundPixmap() instead of QLabel::setPixmap() to draw the background image 
There are some ideas left to improve UMTSmon, some really nice features, we will see if and when I find the time to implement them ...
