PDF Editor > Fillable PDF Form: Possibility to reduce the Line Spacing to 0 px.

Ok, I am using the PDF form builder.
Now I have a different problem. The Layout Settings have a Line Spacing
setting. However, it only offers Compact, Medium and Large settings.
This is not enough. Your Form Designer allows the user to squeeze Line
Spacing down to 0 px.
The PDF Builder setitngs do not allow me to squeeze up text. What
options are available in the PDF Builder to do this

Unfortunately, it is currently not possible to reduce the Line Spacing to 0 px. I will forward your request to our developers. Please note that we cannot provide you the exact time when and if this will be implemented. If there is any update we will inform you via this thread.
