Thanks for sharing. First let me say, you are a designer. You take two pieces of information put them together into something new and unique. No matter how it may be similar it may be to other items it is still uniquely yours.
Unfortunately, I am not familiar with designer and have just started working with AP so there is learning curve there. With PP I have found it to be quite good for the level at which I used it for scroll saw patterns. There are some features like being able to select transparent colors in PP that are not in AP. The biggest problem that I have had AP is finding where things are and how they work.
I do understand the confusion from the videos. Sometimes I think the individuals who are doing these forget that not all of those viewing them are experienced in desktop publishing software. This software has a language/jargon all its own. I want to learn it and use it, however the explanations are so fast and the courser move so quickly cannot follow where they clicked (before anyone gets their backs up, I do understand that I barer a part of personal responsibility for this difficulty).
What I have done to adapt to this speed thing is to open the tutorial in the browser, play it when an action is required pause the video then go to the program and complete the action and return to the video for the next step and repeat. I eventually learn the process.
I do not know if this helps any, but it's the best I have for now.
