@Linda_Doyle thank you for sharing your thoughts.This is a problem that the dev team is aware of. You are right that Zotero does automatic sentence case, but that has the problem of converting proper nouns to lower case. In the new web app, for which we will be calling for beta testers shortly, it will be easier to change the case of a title to sentence case in the Edit metadata dialog. The new web app will use AI to automatically detect proper nouns, so we hope that it goes some way towards solving the problem.
