Sorry if I missed it, but I searched in the .pdf as well as the github documentation and was not able to find a reference regarding exactly what the number/unit values in the text box options represent - Height, HSpace, VSpace. Even though I have mm chosen in the settings menu under units, that does not appear to be relevant for the text settings. If I input 40 in height, the text is 29.08 mm high. 40 pica equals 169 mm. 40 points equal 14.111 mm. If I set the spacing as 10, it puts a spacing in of 3.632 mm.
Typing in “40 mm” into the Height box does not work.
