The key to this new UI feature is scaling and slots per row.
I’ve organized mine based on my spells and shit I don’t need.
On the right I have a box of things that are my class abilities based on using stealth and techniques. On the left I have a group of speeders, sprint, qt etc.
I scaled my bottom bar because I use that for clicking because I hate key binds.
The rest is just for aesthetically pleasing looks.
