LaTeX and InDesign can both create a PDF with bookmarks, based on the headings structure or other styles. (InDesign has a nice 'Table of Contents' function for managing this.) This greatly improves PDF usability.
Just trying out the Beta, and looking good so far.
However, one of the most used features (for me) of PagePlus over the years was the ability to create fillable PDF forms. I'm often asked by clients to create these fillable forms, and PP does everything I need. Single and multi-line text boxes, check boxes, drop boxes, list boxes, date boxes (with calendar), and much more.
Will the final version of Publisher have these options?
