Especially for big documents, it's a must.

I use InDesign to create PDF portfolios of my work. Sometimes, I'll undergo a re-brand and create/alter new styles, but it's difficult to tell where certain paragraph styles are used. This feature would help a lot.

This would help immensely!

I would definitely love to have this feature, to clean up files being handed off from one designer to another, and to identify if a style is applied within the layout or just on a pasteboard item.

Yes please! I am actually surprised this doesn't exist already in 'Find/Change' as a tab and that it doesn't have a shortcut in Paragraph Style palette corner menu, the same way there's 'Find this colour' in the swatch palette corner menu.

YES, I was about to post this! I was trying to organize my paragraph and text styles in a massive shared document where text is added by less experienced users who aren't aware about the importance of styles. I needed to go through a 200 page document to add paragraph styles to make a TOC. The path of least resistance to tell if something was an active style or a duplicate that is used in one section only, was to delete that style. Then replace it with a different massive font style and see how many things got overset. This is a terrible workflow, but it did the job without needing me to google. Highlighting it would let me know in a document what parts are correctly formatted. Especially as a lot of the documents were formatted without using any styles, and going back and updating all the text is a nightmare. A version of the style override highlighting that differentiates between styles would be incredible.

yes this!!

Agreed! This would be helpful for cleaning up files before handoff. I sometimes have styles that appear minimally within a document and I want to be able to quickly identify, alter and/or delete them.
