Chris, please see below...
First a add a text document as suggested by walt.farrell. The two sample images are embedded so you can handle (move, resize etc.) them.
I couldn't answer you questions yesterday because I did not know by heart, sorry. But now i am on the PC:
Astonishing: I actually cannot change vertical alignment of the text. But I remenber I have set vertical alignment to "Bottom". You can see this on the screenshots if you have a look at the baseline grid too.
I cannot check baseline grid too at the moment. Baseline grid was (manually) set to use baseline grid when i begun the text document.
Do you mean "In Textrahmen umwandeln" as screenshot 6 shows? Semms to be expanded because its greyed out.
I am an advanced InDesign user but this seems not to be good enough. I support any serious alternative of Adobe product, so I did purchase Affinity Photo and now Affinity Publisher. And I will try hard to change from InDesign to AfPub. But as I am working most of the year on my books with InDesign to get printable PDF to the printer it must work in every cased. I can change my workflow a bit but I cannot work double time. Therefore I ask after trying all things that - in my mind - could have taken effect.
And I am working with a German version - this is a problem for explainations too. Thank you for your support till now!
