I feel so stupid to ask this, but I don’t seem to be able to create a new Plot Line. I’m using a manuscript plot grid, and somehow I was able to add one plot line. But I cannot make a second!
If, in the left-hand panel, I select the big plus sign to at the top of the panel, “Add New Plot Line” is grayed out. If I click on the plot title for my book, right above the two plot lines that are there now (the one for scenes, and the one that I was able to create initially), “Add New Plot Line” is grayed out. If I click (left or right-click) anywhere in the grid area, nothing happens—no context menu, no pop-ups, no plus signs, nothing. Clicking on the words already there do nothing more than open a card already there.
What in the world am I doing wrong?
