Ik heb dezelfde klacht over de UI. Where previously all buttons and windows were designed with neutral colors (grey, blue and green), it is now a high-contrast pink color. It looks awful.
I contacted support, but they responded with a response that boiled down to this: “Pink is our branding, so we’re not going to change that. Your comments will be noted.”
On forums I also find many complaints about the new color palette. To the developers: listen to the users and choose which color to use! Make it a setting, or restore the colors to the way they were before.
For now I have rolled back the old version.
