I agree with your view on Apple Pages. Once I discovered Convert to Page Layout mode I began using it often on the iMac. It’s become my ‘go to’ app for new projects but InDesign is used when opening older projects so I don’t have to lay them out again. The wonderful thing about using Pages on a Mac is that you can take it on the go with your iPad Pro. I’ve saved so much time and gotten so much done in remote places like the doctor’s office or while visiting a school in North Carolina (I live in New York). There are gripes tho. As you mentioned, Line Spacing options are limited on the iPad. I expect this will eventually be fixed. The other gripe I have, for both the Mac and iPad version, is there is no way to squeeze type from 100% to 98% or 95% to force fit a block of copy. With Pages, you might have to reduce the point size of the font. Otherwise, Pages is a wonderful page layout solution - especially when thinking back to the days of PageMaker.
