My suggestion is not related to the app, it’s related to loosing opportunity
As I know you are compete the Photoshop program (main player at least),but the main strength in the Photoshop beside the starter is the education, it’s too easy to get academic training, professional and certification also on the Photoshop.
You have great app and right now the only app on the IPAD have this power and the Photoshop app is not even close but you didn’t take the education seriously and account only on the Tutorial which is great but if you plan to compete Enlight photo app
Please invest in the education courses, its low investment but will make a huge difference
MS office, Photoshop, Autocad,………… All of them have education task
Thanks for your app at anyway, good job
