Currently there isn't such an option. It is a development release after all. But we will take note of this and see if such feature can be added later.

i think you will find it in beta

Just a suggestion then, drag and drop from app menu to Favorites Bar.  So far all the Ubuntu flavors I have tried have missed out on this with exception to Ubuntu Unity Bar.  But Unity is pretty terrible IMHO.  So far my favorite is Deepins Menus.

In Linux Deepin 12.12, you can drop icon from launcher (Your App menu) to Dock.
