I get the impression that theater view is really starting to come into its own, now I just need to figure out how to utilize it.
I imagine that's accurate.
A few suggestions to get you started...
Do as Matt suggests, and also select
Edit for each so you see how they work. You can define the templates any way you like—each applies to the files matching it's search criteria. So instead of having one for video (the default), you might prefer one for
Series and one for
Other video. The configuration of fields for each template is simple, but powerful. You can place any field or expression in any order in the small and/or large views.
The default "Items to Show" configuration may very well not do much for you. This configuration is also very flexible—almost as much so as for views in Standard View. Be prepared for some experimentation to determine what sort of views you're most comfortable with. An interesting way to start is to
Add... Library Item from Standard View. Pick the views you're most familiar with in Standard View—then you're more likely to recognize what's going on with each view's equivalent in Theater View. Unfortunately, these views cannot be modified for Theater View. To define a configurable view, you have to build it on your own. This is a little tedious, but not difficult. The hard part is deciding exactly how you want it to work.
Didn't help. It does now show track names underneath the cover art (I'm pretty sure it didn't before), but does not show "name: " in front of it, like it does for Video.
I don't recognize that behaviour. You might try resetting "Items to Show" as well. Please try what I've suggested above, and then tell us exactly how the relevant template and view are configured.
