I note this one in particular.

It's been pretty useful so far; for example found out that string params on animation events cause a lot of GC allocations.

Make a snapshot, go through some stuff that I think may have a leak, make another snapshot and compare. For smaller leak may have to do this multiple times, but don't see what other options we have.

AI photo/video analysis on iOS is arguably one of the most useful features they've added. So many times I wanted to find a video of the new kitchen or some document, or even to check to see if I have a book on my bookshelf. It's nuts how well it works. It annotates which part of a long video has it.

Numbers are LTR anyway so the chart you showed look more natural to than if inverted.

Most software makes a mess when trying to do RTL layout, so people end up accepting this. Also it may look weird to flip the whole thing depending on the bigger context. This is readable and doesn't have any serious issues, so maybe it's best not to do more changes.

Yes, technically you would want to flip the whole thing so that the checkmarks are on the right (which is kinda bothering me), BUT I've seen worse in some official documents, so this isn't that bad.

To me it looks fine.

WindHawk is also a good tool to bring back some of the old taskbar features: windhawk.net

One thing that is not talked about enough is Affordance. Level/interaction design in games usually is pretty inconsistent and it adds to the confusion

Hate the material on the XB1 Series controllers. I have Elite2 myself and it's pretty nice to the touch.
