Is there a pdf manual available anywhere for DT3? I see the manual for DT2 available here:
…but I do not see any manual or other documentation for DT3
No. The documentation - which is also part of the beta testing - is only the internal Help. A PDF will be issued in the future.
I’m really looking forward to a proper manual, but I’m just delighted the application has been released 
. Thanks for the clarification.
