Why UM is my only preference for an OS

Thoughts & Feedback

The fact that I can have as many GUI's as limited by my imagination is the reason why UM is my only choice of an OS--I have nine different UI's and would have more if I could get Cairo Dock to work (I will post the error messages, but have written to forums before when this issue first appeared). I will include screenshots of the nine different looks--the Advanced Mate Menu looks awesome, and have messed with the file to get program listings in the order I want. I understand this want of many looks is just a preference and may not be a big deal to others, but it is a very big deal to me and I guess a lot of others feel the same way, given that Mate Tweak is a selling point of UM.
Cairo Dock reports it wasn't built for EGL support--isn't that a way of saying my Nvidia 1650, 4GB, that I need for my Steam games is the reason it's having trouble?

Here is the error messages for Cairo Dock:

I like cairo-dock and use it on my UM22.04. My card is Mesa Intel® HD Graphics 5500 (BDW GT2). No proprietary drivers installed. cairo-dock runs fine despite warnings on the startup.
