The most missing feature is to magnify the worksheet and move to see its different parts easily (e.g. by holding and moving mouse):
If you press “Space bar“, your cursor will change to “hand“ icon and then you’ll be able to do that “holding and moving mouse“ stuff 
If you are using a touchpad on your computer, pinch in to zoom out and pinch out to zoom in. With two fingers, slide left, right, up, and down to see different parts of the workflow.
Hover over the magnifying glass icons on the bottom left, and you will see shortcut keys to do the same. On a Mac, it is command + to zoom in and command - to zoom out. You can also hold onto the command key on your keyboard to move around.
