> unzip hidden behind right click or freaking menu button
By default double click or Enter will cause Explorer to peak into .zip files, which is more natural to me as I might not want to unzip the whole file to see the contents.
> rename through right click or f2
The fact that in Finder the Enter button does not actually enter a directory or run/open a file but let me rename it was the biggest surprise. I personally rename filesystem objects rarely, while I 'execute' them all the time, it does not make sense!
> quicklook on Mac is the single greatest feature ever. Mainly because it works in file dialogs. (...) Windows afaik has no equivalent
Fully agree - it is a very useful feature. Explorer also has it under 'Preview pane' name, but it's disabled by default. I think that Mac version is better, because if I remember correctly it does preview PDF files, while Explorer does not. Other typical files work fine.
> somewhat related, maximum length of file paths.
Fully agree.
