I have not played with Scribus for a very long time. My interest in returning is to build clickable form elements. But I can't seem to find a newbie interactive PDF tutorial for Scribus 1.6.8 on Ubuntu 22.04. Moreover they must be custom forms and I know how to use Scribus Generator to customise. Under Windows, PDF Tools is enabled. But where is the "PDF Toolbar" explained in tutorials?
I am considering doing this in two stages if I can't figure it out. First stage customised but static Scribus PDF. Pass to MasterPDFEditor or perhaps Adobe to overlay clickable elements. Is that the way to proceed?
