I have two problems when using Groupy for my Office 365:
The first it there a little white space under the Tab bar as the image below

The second is when windows in dark theme, the tab bar color didn't follow the office color title bar anymore like in the light theme above, it just shows black bar which is so ugly and inconsistent.

Groupy not used to act like this when I first buy it, if it is a new feature then I demand an option to turn it off since I tried all the setting in color including "automatic" but nothing really can keep the title bar color in the dark theme.
I hope you will fix those two problems soon. 💪
