I have added more controls (combobox, checkboxes) and pictures to GRASS modules in QGIS. http://mpa.itc.it/radim/qgis/grass-tools2.png The pictures (SVG or PNG) can be created (this were created) in QGIS map composer. Each module can have 1, 2 or 3 pictures, which are composed to p1, p1->p2 or p1+p2->p3. Radim
