Videos in a folder - open one with space bar - stretch it to a bigger size (almost full screen) - use arrows to scroll other videos - every video is that same bigger size. No problem.
Pictures and .gif files in a folder - open one with space bar (Quick Look) - stretch it to a bigger size (almost full screen) - use arrows to scroll other items - every one is original size - too small.
Full screen mode will work for one item only - but not the next - even in slideshow mode. In full screen/slideshow the first pic is full screen - and the rest are original size (too small).
This was not a problem in the previous OS. Current OS is Mojave - I was previously using High Sierra.
I can't be the only person annoyed by this. Quick Look and slideshow used to present every item - pics and .gif files - full screen - or whatever size I'd set - and now they won't. That's not progress. That's going backwards.
How can I change this? Is there an app for this?
