How do you dock the comp panel again?
i know this has probably been mentioned a million times here, but one of the more aggravating things for me in AE is unlike PSD, when you undock and dock panels with ease, it just seems extremely difficult to do in AE. See image below:

the comp panel is undocked and i've looked everywhere to learn how to dock it again but have just not been able to figure it out. i just basically want it to be docked again vs floating as seen above.
can someone tell me how to do this? thanks.
