Helo.
I made some adjustments in the menu css,
Basically I modified the size and spacing of the text.
I liked it because I have more options available without the need to scroll.
Another problem I faced was that in my language some texts did not fit and that bothered me.
My amendments are commented
The modified file was “dashboard.css” that is in the “\theme\default\css”
hope you like
