New UI: First impressions (Huh?)

This is so bad. So many things not functioning yet. I had a carefully crafted UI and now I can’t get even close to what i had before. I just lost an hour trying to customise it. Don’t care about Mac, I had it and didn’t like it and never considered it as a friendly interface and i see no pint in taking inspiration from there.
Examples:
Why I can’t have these icon in horisontal layout?
Why are they smaller than the other?

Why the heck I can cover the icons half-way? Why there are covered anyway? What is this thick border for?

Image and text are not displaying

Reorganising order of toolbars is beyond my skills:


Why these panels (using the same toolbar icon) are separated? It’s a waste of space.

There should be effort put on optimising what was wrong before and then creating new UI. Now you are adding errors on top of previous errors.
There are plenty of things that annoys me so far. I hope it will get better over time but for now I have to drop WiP again in order to have my productivity back.
