I use long titles to help me distinguish between scrivenings. If you do a search the title is the only thing that you can see without selecting a scrivening. It would be nice if the title wrapped around in index card mode instead of being cut off.
Under the “Corkboard” pane of Preferences, you can tick “Allow two lines in title areas” and “Automatically shrink titles to fit with a minimum font size”. This will allow you to see more of the titles in the corkboard if you really want. It’s not designed to wrap them beyond this, though, and will never allow wrapping over multiple lines (more than two) - that’s what the synopsis is for, after all - but this should do pretty much what you want unless you have titles of hundreds of works.
All the best,
