Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
We are pleased to be able to provide the new Lot Pinning feature based on the suggestions of one of our users! When a Lot is Pinned, it is stored in a persistent list, with quick visual reference to the Sign, Sign Lord and Term Lord; and allows you to name it anything you like. Once Pinned, the lot configuration can be recalled later to access the details without having to (re)enter any placements.
Stana, thank you this was a great idea!
