Depending on the project, it may just be updating a few labels all the way up to 200+. Currently I am putting together 3 projects with 25, 60 & 247 labels so it can vary.
They are rectangular text boxes with a frame around them (cutting line for printer).
The text is of varying length, from 4 - 15 lines of text, this is inherently the obstacle. If they were all the same size I could choose the best sheet size to maximize coverage. Below are examples. See how the page on the left has unused space at the bottom. I would like a plugin that can search the document for another text box small enough to fit there in order to use the space, like the right page.
