So, yeah, this is probably old news to everyone else, but I’m late to the party, as usual. I finally tripped over two menu options in the History menu of Safari that I had not previously noticed.
The first is “Reopen Last Closed Window.” This is very useful.
The second is “Reopen All Windows From Last Session.” This takes care of my biggest concern regarding session restore.
So I guess maybe a “Reopen Last Closed Tab” option might be about all I could add to that to be truly complete.
I do still look with great envy at Firefox’s extensions system, particularly for Adblock Plus, FlashBlock and NoScript.
