Use normal but semi-transparent color instead of 'disabled' color for counts drawing. Do not leave empty space for icon when selected item doesn't have one. Use null pixmaps/icons instead of non-null blank ones. Implement our own sizeHint and minimumSizeHint to make sure both combos have the same height. Make activity combo width fixed, tracker combo width to fit its content and line edit to occupy the rest. Add 'Search...' placeholder to line edit.
