You can now create a Heesch tiling by selecting "New Heesch Tiling" under "File". Information on Heesch tilings can be viewed by selecting "Heesch Tilings" from the help menu. All 28 Heesch tilings are supported; Heesch tilings are symmetric illustrations that use a single type of tile to fill the plane without gaps.
Translational symmetry vectors for the current symmetry group can now be shown or hidden using the "Show Translations" menu item in the "View" menu.
You can now adjust the translational symmetries used for wallpaper groups. First show the translational symmetry vectors and then move the non-vertical vector's head or stalk to adjust its length or orientation; single-clicking will allow you to enter a numerical value.
