Yes please!! If it's at all possible to open .indd files would be awesome. I just tested Affinity Publisher Beta, opening a PDF that I had originally created in InDesign and it kept all the fonts, formatting and pictures as my InDesign file. This isn't ideal, as I would need to save every InDesign file to a PDF, however, at least it is an option. I'm quite impressed so far with the Beta version. Looks very easy to use and everything is easy to find. I'll be excited to move over to Affinity Designer and Publisher, however, I'm not quite ready to give up my Adobe Photoshop. I'll give it another 12 months while learning Affinity Designer. I think the main problem with Adobe, is they haven't catered for the people who used Creative Suite - Photoshop, Illustrator, Indesign and Acrobat Pro. It's very disappointing that we have to pay for 'All Apps' per month subscription. I have a feeling Affinity will take a large amount of 'print design' creatives from Adobe ;)
