Added simple notes and a help email (reportmybug@gmail.com) Known bugs added to backlog: Datacubing from a post node may not always work Windowed mode needs a fix Dev note: Thank you for trying my software. This simulation may be difficult to grasp, but I will keep developing it and its partner app WonderMatrix. Currently my PC is below the requirements so it makes development tedious, but I will continue the work more deeply after the new year. Please submit your requests so that I can prepare/improve. Thank you again. S.W
