I created my chotbars to be comfortable, practical, and aesthetic.(to me anyway) Nearly all same/similar skills are in the same position across all jobs/roles while allowing for as little finger gymnastics as possible.

My XHB is split between chotbars 2(left) and 7(right)

From Bun Boss video but slighly modified

Machinist hotbar inspired by bun boss on YT, but made some changes to align better with my DNC layout

MMO mouse setup with modifiers.

Nothing changes

Waiting for the new action images to get added in to fully get this good

Make sure to change Double tap L2 to "Cross Hotbar 4 - Left" and Double tap R2 to "Cross Hotbar 4 - Right"

Test

General use MCH hotbar for quick access to some macros if needed.
