I too think this is a really great compromise, and after using it for just a few minutes, I've come to really like it. I
can actually build nice complex playlists on the fly in Theater View. That was never something I necessarily aspired to, but now that I
can, I think I
will!
Mindful of Larry's concerns... Larry, I tend to agree with you on general principles. For example, I despise the "hide items you haven't used" features that Microsoft seemed to fall in love with there for a while, and disable those features immediately.
However, this is slick. The rest of the menu is static. The only item that changes is the top item (the Double-Enter item). All other choices remain available in the same order and location. This makes it easy to quickly and painlessly choose what "double click" will do in the Theater View context, and then switch to some other "file playing" motif another time (in another situation).
So, if you always use Play (All) or Play (Single) or Add then it'll always stay that way. But, if you happen to decide to build an on-the-fly playlist (where you usually use Play All) then you can just DO it and not have to dig into some menu in Standard View that you can't read on the TV! Usually, if you're going to be building "on the fly" lists, you're going to want to Add or Add (Next) over and over again. Then, later on when you're just watching some shows or whatever, you just pick Play All or Play Single the first time and you're set from there on out.
I like it a lot. Hopefully others will too. I'd say, worst case, add a
Options --> Theater View --> Behavior --> Remember Last Used Play Style as Default Action choice (defaulting to enabled). I'd say if you give it a chance, you'll probably like it.
And, "Play All" doesn't make sense when the option is given for a single item does it? Shouldn't it be just "Play"?
This is a pretty minor quibble. I'd guess they'd have to add annoying logic to hide the Play All choice only when viewing a File-Level list with only one choice (so everytime you show the context menu it'd have to check the Play All item against the number of items in the collection to be displayed). Play and Play All just do the same thing when that happens, which I'd say is obvious and intuitive!
I agree that it's a bit confusing in Playing Now though. So, basically, true and true, but certainly minor "tweaks" and not worth losing this great compromise!!
