Premiere Pro Surprises

How are you getting used to editing on Premiere Pro? What surprises you about it? What challenges are you having?

I am starting to learn a couple new keyboard shortcuts, mastering the use of c,v, i, o, and '. I understand sequence types to a certain degree and I am starting to understand basic color effects. I was surprised that the audio file is always separated into two, and I have yet to figure out why that is. I was also surprised that logging is an important part of editing, because it seemed like a long and unnecessary task when dealing with short films. I am still challenged by management of files. Everything because very confusing when a shot is identified incorrectly. I am still trying to learn new keyboard shortcuts, because I accidentally press an unknown button at times which causes unknown effects on the timeline. I continues to struggle with time controls; I am still trying to find where the speed curve is located.
