Hello iMore,

If you could pick only 1 feature of OSX Mavericks to be your favorite what would it be?

For me it's the Maps Application, I love being able to send Maps to my iPhone.

Improved multimonitor support for me. I use full-screen app mode on my macbook air quite extensively and it's great to be able to retain this feature when I hook up my macbook air to an external monitor.

Tabs in finder - Helps me a lot in multi tasking...No need to open new windows to transport files to other folders...

Worst feature should go to the mail application

Tabs for Finder as well.

I'm gonna say Maps. Use it a lot, nice to have it right in the dock, so much quicker than via a browser. And the maps are beautiful plus routes can be sent right to my phone. Good stuff.

I wish it were a little more intuitive; I find the behaviour of opening the app in the active window a little annoying, especially since I usually launch apps from Alfred/Spotlight.

Improved memory and power management.
