Tom Lohman has developed a new index wheel that supports 180 segments per row and I had agreed to see if the software would support this. I had to make a few changes I wasn't expecting, but it is now working. However, don't be surprised if you run out of memory if you use 180 segments on too many rows. It is all based on how much Random Access Memory is available on your computer but I have gone up to 14,000 total segments. Also, be prepared to wait as it takes a LOT of resources to manage the painting of all those segments.
