Where the text zooms when zooming in isn’t a problem that I have issues with so if you would like to fix it or leave it for another time, is not a problem as far as I’m concerned.
What I did mention is that when creating the label, you can choose the font size but this seems to work as a percentage of the label size and the longest sentence in the label, rather than points (pt) as in MS Word:
Here my label width is 10cm:
While here it is 5cm:
I didn’t go out to adjust the zoom.
So this makes it really difficult rather difficult to maintain a constant font size throughout the pattern. One can only guess at what size to make each label so that they all look the same.
However, I’ve managed with it this long, so I’m used to it. It just seems a strange way. I would’ve thought that the width of the label should adjust to the size of the longest sentence.
I hope this helps you.
