Describe your proposed solution

1. Notifiction button was placed near the Close and Maximize. Close and Maximize are linear and non-background icons, but Notifiction icon with a white background. Can their display styles be unified?

2. The black icons in the sidebar are not clear against a dark background(like the green mark on image).

Describe alternatives you've considered

This is a UI design issue and doesn't require an alternative solution to instead.

Additional context

None

The dark icon might have been forgotten during our removal of left bar (addition of auto transparent left bar) so the UI button in light mode is a bit occluded/hard to see on certain background.

@shatyuka can you help me on this one? I'm still confused myself reading the main app theme xamls
