Imporve workflow - piemenu, sortcuts (there was such project) or "S" menu, more options under right click including "OK" and "Cancel". To many kilometers with mouse are now needed to operate FreeCAD.
Sketcher - offset, section plane on sketching object, snapping to the parts "under" sketcher, constrains under right click (or popup), querry before exit sketcher by pressing Esc button (this is very annoying).
Model - section view needed.
O/A - double click of middle mouse button = zoom all.
