This question serves to share and collect the enhancements which are not documented by Apple, or documented poorly.

Please justify your answer; if it is something that is well documented by Apple and elsewhere on the web, it does not belong here. Your answer should put the feature into context, explaining how to use it. Add a picture if necessary.

Please add only one topic per answer. Try to find and edit existing features / answers rather than posting a duplicate answer which will end up getting deleted. Note that answers which are not specific to Mountain Lion will be removed as well. You can post such answers here.

    @GnomeSlicE We've done these type of wiki collections several times in the past. While they are disputed, they always receive a lot of resonance. It's better to avoid them, especially for little things. But as Apple does not document everything they introduce in their software this question can be useful to many. Feel free to discuss these type of questions on meta.

'Do Not Disturb' Mode for Notification Center

In the Notification Center drawer, scroll up a bit past what appears to be the top. There's a switch 'Show Alerts and Banners' that is checked by default. Uncheck it to disable notifications for the rest of the day.

Alternatively, option-click on the Notification Center menu bar item to activate Do Not Disturb mode quickly.

Exposé for all windows

Mountain Lion re-introduces the pre-Lion feature to be able to disable group by application in Mission Control, this was enabled by default in Lion and could not be disabled.

You can disable this in:
System Preferences → Mission Control → Group windows by application.

Mountain Lion offers direct video/audio encoding from Finder.

Select one or more audio/video files, then right-click and choose “Encode selected video files”. You’ll get something like this:

Note: this doesn't work for already compressed audio files (like aac and mp3). This does work for CAFF, AIFF, AIFC, S2df, and WAVE as per the -2700 error message that shows up if you attempt this on an already compressed audio file.

Also, this may be found as a Sub-Menu Item of the Services menu (contextual or from the File menu) for those with a number of third party service actions enabled/installed.

Additionally, this does not preserve meta data like locations of movies or ID3 tags for AIFF files, etc!

Show scrollbars without scrolling

If you have a multi-touch input device (a multi-touch trackpad or Magic Trackpad), resting two fingers on the device will make the scrollbar appear as an indicator of your scroll position. You no longer have to scroll the document to see where you are.

Note: doesn't work with Magic Mouse.

Photo Stream and other screen savers

Re-enable Web Sharing for individual users

May be more a "feature" than a feature, but anyway:

Per-user Web Sharing is gone from Preferences but can be easily re-enabled via Terminal.app. Copy the following snippet into /etc/apache2/users/USER.conf:

<Directory "/Users/USER/Sites/">
    Options Indexes MultiViews
    AllowOverride AuthConfig Limit
    Order allow,deny
    Allow from all
</Directory>

and restart Apache with sudo apachectl restart.

AirPlay Everywhere

AirPlay devices like Apple TV and Airport Express now show as system audio output devices, so any audio on your Mac can be streamed to them. There are two ways to do it.

The fiddly way

System Preferences > Sound > Output

The easy way

option-click on the volume control in the menu bar

Three-finger tap for QuickLook

Tap (but don't click) with three fingers over an item in Finder to open QuickLook for that item. Tap again to close the QuickLook window. This is exactly like pressing the spacebar.

Slightly better Dock appearance

The Dock "shelf" (when the Dock appears at the screen bottom) is drawn in a less glassy way (looks more like brushed metal, less reflection, less wasted space).

Also, the active appication indicator lights are much more subtle that the glowing "orbs" that used to sit on the glass and look awful, and now look like little LEDs set into the edge of the shelf
