Immersive dock

[Unitedmetalheads]

Hello. I used to use a dock on my rainmeter which was vertical and had circular icons. And it used to be hidden in some place of the desktop and upon mouse hover, it showed up and i could open an app and then it would hide back again. It used to have a plus sign in the middle of it so that i could add more shortcuts. But i forgot to take a note of the name of that dock and dont have the rmskin file anymore. Can you please help me find this dock according to the things mentioned above? Thanks in advance.
