Dear all, Rainer's suggestion was inspiring! Early this morning I got up to create a checklist for the PHP interface. It is there along with a new version of the "php" folder fixing minor errors while doing the documentation: https://leti.lt/bolprocessor/ The aim is of indeed to explore all features and get a minimum of understanding of what is happening, or what we are in the process of developing… You are invited to modify/comment this document — and fix language mistakes! I am careful implementing "undo" procedures whenever it is easy, which was difficult to do on the older versions. I am now working on this issue of startstrings and item playing, trying to make our lives easier! ;-) Bernard Anthony Kozar wrote on 28/07/2020 12:30: > Yes, these features are on the "to do" list.
