Moodle is a great tool. One improvement I would love to see is a "side-by-side" feature that allows teachers to preview their changes on the same screen as they work. This would greatly reduce the number of clicks that instructors when editing and creating activtiies.
An example of a possible solution is something like the workflow in Windows operating system environments. See screenshot below.
I imagine that the new moodle feature or perhaps it could be a new moodle theme template (?) could have it so that the user can see the "settings block" on the far left. THey could edit in the middle column, and then they could see a preview of how the page will appear on the far right.
Another option could have a preview "toggle" on/off switch so that the instructor can see how their changes would affect the page before they click save and return to course.
If this already exists, please let me know. I'd love to explore easier workflow options.
