Heya, i like how you try to improve, yet, i question if you have User Experience designers in your team. This is not meant as an attack but my honest curiosity.
I did not try out the new UI before the opt-out phase since i wanted it to test on one client. Yet you have the remaining isuue that if i make adjustments on one client it affects all clients I tried Photon on one client on Singularity and it affected all other clients. booo!
Since the new UI is Opt-out i had these issues with it:
The new Ui is too bulky and especially in the cargo hold window, informations overlap, due to big fonds, huge symbols and to big unused borders. compact mode does not have a seach function, otherwise it’d be perfect. Old UI is better here.
Docking does not work from the radial menue when i interact with the station in space. Radial menue has been not working constantly (especially while multiboxing) ever since, but i love it and would love to see it work reliably. Also radial menue does not work for warp and dock with a set cource when i am in the target system and interact with the hollow square (just warping works, usually) in the set route.
The drone window does not let me adjust the distance theween the two headlines “drones in bay” and “drones in space”. i’d love to have the distace minimal. seeing drones in space is more important to me than in the bay. i want the window as small as possible and still see what the drones do atm.
Overall performance has decreased. Between giving a command and execution there is up to 3 seconds. :((( Eve Online felt already slow for an online game, before this.
Higer security LowSec Systems can’t be indentified safely with the new Sec status colors. 0.4s look still like HighSec. Definitively a step backwards in terms of clarity.
Probably there is seven other things that i am missing right now, but there is still a lot of work to do and certain topics should be reaproached completely imho. Maybe start redesigning the sound layers, so players can crank up wormhole and gate activations without going crazy over the station humming. Also use the opportunity to fix the issue with setting one client’s sound (i.e.) and all others are affected, same with the UI. Different toons do different things and need different settings. You might implement an easy way to copy setting without playing the .json-game. 
Please get that UX designer and listen to them.
Love and hugs,
a player
PS:
You made it harder to filter the Personal Assets for region (needs more attention/clicks)
Recover Probes and Solar system map buttons in scan probe window are too small, signal str is hidden, scan dev and scan dur can be in one info window. Replace the icon by value and give the additional info when hovering the mouse over it (like now)
