You know, sometimes spreadsheet / properties fields of a pieceare not sufficient. It will be good to add graphical sheet property to a piece. It should be similar to map window and intended to place more pleasant and often more comfortable picture data sheet with unit stats, supplies/ammunition tracks etc, and some counters to move them along the track, etc. Actually it should be a standard map window, but instead opening automatically or on button it should be an element of a piece and be opened via hotkey/rightclick menu. INaturally each piece of the same tipe should have its own instance.
Without such Graphic chart it is almost impossible to make a normal module for a number of games like Battletech, Full thrust and other games which use complex datasheets which cannot be reduced to spreadsheet/properties.
