Now that the Android Q Beta came out in a couple of days, people managed to dig and find new features that Google did not mention in their official message.
One hidden function in Android Q is the experimental desktop mode. Found Shad0wKn1ght93 on Twitter and XDA-Developers This feature allows you to turn on the Samsung DeX desktop with Pixel phone, as well as the ability to add shortcuts to your desktop and launch freeforms. If this feature is enabled, the status bar and navigation bar remain unchanged, but it is still in beta.
You can try this desktop mode by going to the developer settings on the Pixel phone with QQ "Desktop Mode" and then launching the Pixel program using this command: adb shell am start -n "com .google.android.apps.nexuslauncher/com.android.launcher3.SecondaryDisplayLauncher ".
A feature is the ability to set the clock on the lock screen. At the moment, there are three choices in addition to the usual digital clock: a text clock, a bubble clock and an analog clock with long hands. These clocks are incomplete because they do not show the date or the weather, and in the case of bubbles and analogue clocks, they also show digital time. Again, it's still beta.
The good news is that if you use one of the other lock clock parameters, they will work on Always On Display with Pixel 2 and Pixel 3. 
Google announced several new features of Android Q when it launched its first beta earlier this week, including better complex support, better privacy and faster sharing. There are many other new features that are scheduled for Android Q, although we will probably learn more about them in the official Google I / O format in May. Until then though, there will be a lot of people digging into the beta and finding new features hidden by Google.
