This new look is worth a try. It may have better features than the old style. Time will tell.
The Members List is ever so much more readable and attractive, IMO.
And you can choose from 4 font sizes, down at the bottom right of the screen.
If you're seeing a blank white panel at the bottom left of the screen, it's probably because you're using an adblocker. If you turn the adblocker off, you will probably see an ad.
I'm enjoying the plain white panel now that I know it's there instead of an ad. At least I'm not seeing the ad.
