There are some slideshow tutorials in the Help menu. Have you looked there?
Also, videos are not simple (nor necessarily cheap) to produce and updates to them aren’t so easily done. We may look at it again but the help and manual, tutorials, these forums, and our support ticket system are the resources available now.
It’s kind of a waste to produce videos if there already are a lot of good ones out.
Try this:
It is well worth $49 for over 8 hours and 100 videos of serious education. No ads and I have “known” David for at least 10 years. Very serious and pedagogical. Also have videos for very many other apps I use. This is for version 3 but if you go through this you have a very good start to use 4.
If I had this when I started with DT2, it would have saved me a lot of time. I can also only recommend this course if you are a “video type of learning person”.
