Hi Giuseppe

That's a good project, thanks for getting started.

On the subject of the UIs in .ui files, I would hope that they scale 
automatically for HiDPI screens. All the dialogs and windows should be using 
layouts, which will automatically increase in size due to the increased size 
constraints of the text and images. The only two things that come to mind that 
will not automatically scale are:

1) the total size of the dialogs and windows (they will only grow to the 
minimum size, which may look ugly)

2) the graph widget and the table column widths

The graph widget should be modified to realise it's in HiDPI and draw things 
twice as big; the column widths should be modified to have a width proportional 
to the font size (i.e., measured in ems instead of pixels).
