Hey @HereComesTrevor,
Just recorded a tutorial on user-specific filters. You could use this approach to have not dozens but one page with a filtered subset of data, and a user-friendly, user-specific control panel in the top so that each user would independently see their own size/style. I.e. instead of users going to different pages, they’d go to a single page but see different stuff independently.
A good practice with Coda: you only create new pages when you actually want to have a new perspective into your data (e.g. a differently grouped table). Simply duplicating pages to show different subsets of data is not a good idea, specifically for the reason you described (changes in UI in one page don’t propagate to other pages).
Cheers!
