I think my gripes so far are around discoverability. How did you know to click and hold the space bar? Now that I know, I like it. Never would have know otherwise. Drag from the bottom left and up to dismiss an app, do the same but go sideways to get to history of apps, etc.
Not sure what to tell you. I did not dismiss any tips that I can recall. I recall how to create folders and drag apps to it from onboarding. Mostly, I have to ask someone or search Google to find out how to do the most basic of things.
