Oh, on this – I changed default to white for the moment. But you can select light, dark or blue under: preferences / interface and then the theme drop-down .
The preference is the gear under your user icon in the upper right.
I prefer the blue one tbh
Yeah, but this only has a major impact on the unregistered users (as three clicks lets you fix it), and I think the white is a little easier on newcomers. The blue is still available to you and all who miss it.
This is so much better
