Rhino7 toolbar pallette

Lashed out and bought the discount upgrade (Thanks for that McNeel!).
Trying to replicate the left toolbar pallette to the same as my Rhino5. I can change the size of the icons (preferences), but I need help to arrange the icons so there are 4 columns, not 5 as is the Rhino7 default.
Also, not so keen on the shortened layer naming in the right sidebar. Can I change that to replicate the older style?
