Hi all, I second that request for at least partial InDesign support too.
I have paid Adobe CC complete package for couple of years now and I'm getting tired of theirs pricing policy, specially when using only couple of apps of theirs: Photoshop, Illustrator, InDesign, Premiere, Audition, Lightroom and few more occasionally. I have been using these products for last 25 years quite happily. But with CC, everything changed.
Thanks to Affinity and Apple, I have substitutes for almost all of Adobe SW I use on regular basis, but InDesign. I have learned about Affinity Publisher just today, and I jumped in excitement that there might finally be a way out for me I don't really need full indd support, just to convert my older files and live without Adobe for the rest of my life or until they introduce more flexible pay model.
For those looking for similar switch from Adobe, here is what I'm quite satisfied with.
Illustrator > Affinity Designer
Lightroom > Apple Photos, Apple Aperture
Premiere > Apple iMovie (limited, but good enough for me)
Audition > Apple GarageBand
Dreamweaver > netBeans
Photoshop > Affinity Photo, Apple Photos, Apple Preview
