Drag & drop /rearrange periods when using a copy of the last year's Planbook (setting it up for the new schoolyear).
If I taught ELA during PERIOD 1 last year, but ELA MOVES to, or I must teach it during PERIOD 4 THIS year, I need to be able to easily DRAG & DROP or rearrange periods to different places within the day--for the year. This means that MOVING ELA from Period 1 to Period 4 would AUTOMATICALLY make that change: (1) for every day/week in the new plan's school year (also moving the previously typed plans). And (2) the period numbers would change TO REFLECT the new placement--ELA would now say PERIOD 4 for the rest of the school year. It could be similar to the concept of working on a "MASTER SLIDE" used in Google Slides or PowerPoint.
