Topic: Zoom enhancements
Multiple "standard coordinates"
Currently Graph can store only 1 zoom setting, recallable by the standard coordinates button. When working with functions, I often need to examine function behaviour repeatedly at several zoom settings. Being able to set and recall multiple zoom settings would be convenient, like stations on a car radio or memories on a basic scientific calculator.
Auto fitting a function
The "zoom to show the selected function" is great but how it chooses the x axis zoom is not apparent for functions with an infinite domain. A common need is to visualize what happens to a function as x goes to infinity. It would be convenient to zoom out x, y or both directly to program limits and also to auto zoom just x or y to fit a single axis.
