Hi Stefano,
Thanks for your interest in and questions regarding MooTyper.
Item 1: If you mean that you would like for MooTyper to automatically reset a lesson so the student starts from the beginning of the first exercise upon re-entry, then NO MooTyper does not have that capability right now, as, a. it had never occurred to me to implement it, b. no one ever asked me to implement the capability. However, effectively there is no limit to the number of exercises a teacher can add to a lesson. So, if a teacher wants to, they can keep adding exercises to a lesson, so that you get the same effect without having to modify the code at all. An easy way to implement this would be to do something such as add each of the Aesop Fables as an exercise into one long lesson. Check Project Gutenberg for other suggestions and copyright requirements. Since every Project Gutenberg book I've downloaded to read, and that's a bunch, is available in, Plain Text UTF-8, a large part of all the work is done.
Item 2: You are correct that currently, MooTyper does not integrate with Moodle's gradebook. Eventually, I hope to make it so, but have other priorities, at the moment.
"If the above is correct, is there any particular reason why that is the
case, other than you obviously not having the time to implement
everything and/or right away?" - 3 main reasons. For the past two and half years, my son and especially my wife, have had extreme health issues which has limited the amount of time available to me for code work. The PHP language was invented just about the time I finished my BS and MS degrees, and I still struggle with it. I hate to admit how much of the past seven weeks I have spent trying to get an audio file to record and then playback for a MooTyper dictation exercise capability. The other reason is that, no one has asked for it. 😁
