Yes, Finder has always sucked. We were promised a "ground-up rewrite" years ago... don't know what happened there.
Microsoft has degraded Explorer, though. For example, you used to be able tell which directories were empty by simply noting whether there was a + symbol next to them. Clever and time-saving.
Now, not only did MS replace the universally-understood + sign with a stupid triangle, but it now HIDES all the triangles unless you happen to roll the cursor into the left pane. WTF, WHY?
Oh, and if you select multiple files in Explorer and right-click to say "Open with..." NOPE! Microsoft inexplicably removes "open with" if you select multiple files, even files of identical type (PNGs, for example).
The opening of multiple files was fully functional 30 years ago. WTF?
