Here's a teaching life-hack I've implemented to help me make ongoing improvements to my class. For each class I teach, I keep a Notepad document called "0_change.txt" in the folder (the "0_" prefix keeps it at the top of the file structure). Each time something doesn't work quite right in class, I make a note in that file. I often don't have time to implement the change at the moment I think of it, so this note includes reminders of where information is or specifically what needs to change. When I prepare to run the class again, I use the file as a punch list of improvements to make.
