I do like the idea of being able to check off and “like” tricks! Currently I use a paper list of all the tricks and elements I’ve learned and I run through them once in a while to keep my memory fresh but an app could replace that.
I also agree on the video section being a bit neglected here. But there’s plenty on YouTube so I go there for the tutorials and here for the chat and store. Again, I guess an app with lots of tutorials could replace that as well.
So basically I was perfectly happy with the way things are until you brought up your good points.
