I think the app telling you these images don’t have embedded thumbnails (which can happen), or they aren’t big enough for a good user experience, with an option to never see the dialog again is a good thing.
Yep.
Grand Central Dispatch is a wonderful thing… when you can use it
I use GCD everywhere, but Apple’s RAW decoder cannot leverage GCD the way you might think. The core problems are GPU utilization and memory consumption which I mentioned earlier. There are always opportunities for improvements, but this is not something that can just be thrown on an async queue and everything gets better.
And I think it is appropriate to say the behavior needs to be different on different platforms
Sometimes. With iCloud syncing and such, the same image will appear on iOS and Mac – if thumbs and previews are drawn differently for the same image on different platforms, then it’s confusing.
And if we differ on that, fair enough
We don’t. However, my workload is zero sum, so I make careful decisions on what to do when.
