Firstly, it works in real time yes, but it's not tracking your mouse etc. so you can take your time, when you run the action it will run through the selection of items you choose, rather quickly. So there's no rush in recording the action.
Secondly, you can delete, move, set the action to be a dialogue box to invoke special settings at certain points.
I'm not going to bother internet searching Photoshop Action Tutorials for you - I think you can manage that yourself.
I usually use my digital pen with photoshop to draw and record the drawing process in an action.
The things is... the action also records, for example, hand moves, or me selecting other layers or tools by accident, ( meaning I have to go back to the action panel to undo the last things I made by accident and slowing the process).
My question is, is it possible to tell a photoshop action to only record my brush tool stroke movements, and no "hand move" for example?
Can an action ignore certain tools? Can I personalize it ?
Yes, I've google a lot of different terms and cannot find anything about what I specifically want.
My english is also not the best so I may be struggling to search it with the right keywords.
How will it know which ones you want to keep? It’s just a dumb application remembering everything you do. It won’t even know if you have made a mistake as you could be using ctrl-z and ctrl-y to check your actions.
