Since my primary use of Pro+ is for making stereograms, I will frequently leave a blank custom template, 6 pages with filled rectangles and various objects I used all the time, open for the next day.

If I do not add anything to the template, it is gone the next day and replaced with my default template. I know I could make my stereogram template my default template but I don't want to do this.

Not a huge loss, but just a little annoying.
