tile builder features

A number of years ago (probably about 3 years but I lost my emails from that time period) I emailed you about a feature that I'd like to see in Tile Builder 1.6. That was the ability to showing (or turning off) symbols of all the symmetry elements that are generated by the action of TB. At that time you responded that you thought that would be easy and that you probably would implement it, but nothing has happened - there have been no updates since that time. I hope that soon there will be another update to 1.7!

With that extra feature, I believe that TB would be more popular with mineralogy/crystallography teachers that deal with crystal symmetry and 2-d/3-d space groups, and also with designers working and teaching symmetry in textile and other 2-d applications.
