OK, but displayed grout line width is innacurate
The app mostly works for what I need, but there seems to be a minimum size grout line that the app displays. I am dealing with 12” square tiles and an 1/8” grout line width. However, the final result shows the grout lines way too wide, closer to 1 inch. This is a bad bug; perhaps the programmer has never tested the app with inch units.
