I am not a cool millennial but I work with book interiors. Have been reading about the nightmares designers have had adjusting the margins of text boxes once there are several hundred pages and changing the master pages doesn't alter the actual position of the text boxes. Can I agree with the comments attached below -- to you Adobe company people -- don't **** off loyal users who were using Adobe before the millenials were born -- PLEASE STOP taking away features!!!!! I have recently updated to ID2021. Am I still going to have this bug -- as I now need to adjust the margins a tad away from the spine having just received the hard proof of a 500 page paperback. Thanks :-)

Again Adobe, the upset stems from your same and recurrent problem (across your product "upgrades"), you don't get it: stop "taking away" features (especially default ones, like you changing the psd default "constraint proportion"... so bad).
Add new options to old features if you think it improves, we'll click it ON if/when it's suits our type of work (or way of working), but don't (why???) take away what's there, works and have been working for ever.

It's amazing the lack of knowledge (or depth of knowledge) you too often demonstrate about how your software are (day in-day out) being used/by whom/and for what kind of projects. Try test driving with people who have been working with them for more than 5 minutes, they might not be cool millennials, but they sure understand Indesign (and PSD, and AI...), and are not confused about "which software" to used for doing "what" well.

For myself, it's sadly the number one complaint I have with Adobe. I use your software every day and find them truly amazing and I think Indesign is the top in it's field.
