What would be even better would be to be able to interact with the formatting of all fields with a few criteria (Bold, Tabulation, underlining, blocks to appear or disappear, colored background...). The ideas are multiple but currently, I think that the biggest problem is when several sections are nested (the titles are all black without distinction!). The second simple and yet effective improvement would be to be able to group/ungroup a section (function additional to “inline” and “drilldown”).

Shading of input cells would be good too: I have often been asked to highlight text boxes (in particular) where the words written by our surveyors get delivered to our client. (We also have text boxes for them to communicate with our office team only.) Both surveyors and our reviewers need to know which ones need the careful wording, so it would have to be evident on mobile and web apps.
