Hello Ann,

A quick question on this one, is there a reason that it is a 100%/60%
toggle rather than allowing the user to set the percentage?

Most of the time 100% is not ideal (even in the case of the OP, it is
just better than 60%). I just wonder whether maybe say a 95% fill
ratio may be better overall in this case, allowing for a couple of
changes on the same page, but also saving on the wasted free space?
