Backend UX is a mess for me

The new role editor in 1.1.8 is brilliant @Louis - It takes care of my personal frustration with the backend. Is it possible change the icons used so they follow the looks of gutenberg ?

And maybe also change the colors and fonts of the Cwicly interface from black to something lighter, but not white ?

Just saw this post:

I hope you respect my frustration as non-aggressive and just an expression of my personal frustration.

Thank you for changing the title of my initial post.
