Not gonna get into the galmap, system map stuff, i'm still working my head around the changes.
But coming from a HOTAS only perspective myself,
I'm gonna differ with you here, speaking about station services and in particular the mission board, the new UI is cleaner and easier although the separation between missions and passenger lounge is a level too deep IMO. But being able to see all transport mission, or all salvage/operations type missions or all combat missions without having to switch between faction tabs makes it a lot more manageable when you're stacking missions and looking for others in a single destination system.
Loadout and storage has some issues relating to context switches, and for many missing info, although being a single ship pilot it isn't something i've had to experience as much of that myself.
Theres some state management problems between layers of the repair/refuel UI and i'm still undecided about that.
Mostly the issue is , it's different. It FEELS like more work because we're fighting accustomed muscle memory, we make mistakes and have to back out of frame X and go back in again. Going back into Horizons the other day i found myself having the same kind of muscle memory clicking the wrong thing at the wrong time problems in the old UI.
But the actual number of actions is rarely more. More trigger clicks instead of thumb flips of the top hat, or throttle flappy panel left-right taps (in my case), more visual context switches.
That isn't to say there aren't problems that still need solving (sell vs store module with sell as the default for example).
And yeah, i'm one of those who complained at first too.
In my case it has nothing todo with muscle memory, it's a visual thing.
Overall the UI arrangement has way to many changes, transition is more steep than seamless.
Apart from that, Mission UI, I agree that it is cleaner, which also is part of the looks, what I dislike is when I as example select one of the mission givers, no mission is shown, where as with the old UI it would show all and let me select the filters
While it is nice to preselect filters as well it should not be a requirement.
I still can't see which missions are legal, where is that purple icon or what ever they mention? I must be blind because I just can't seem to spot it nor set a filter for it.
The complete icon changes are another issue, not even Microsoft changed theirs that much from Windows 3.1 to Windows 10, anyone who works with PCS and other symbol standards knows that you just don't change the image completely.
Maybe not a major issue for us since we can adapt, but there are actually people out there who will have hell of a time adapting.
Also changes to descriptions upon difficulty on top, now I have to learn what the new ones actually are compared to the old ones.
Just had to turn in a mission, blue field to the right with completed mission,hat switch button to the right and it stop just before the field I have to click, have to do it one more time to get there, that is another UI bug which requires double the clicks.
Also the "are you sure" confirmation popups when clicking Accept for each mission are another additional click which is absolutely needless.
Shutting it down now since the GPU fan noise caused by being in a station drives me nuts as well.
