Usability should come first for a UI....
No need to change what's not broken that people are used to, unless your remaking the whole thing to make it more accessible and easy to understand.
Even then you need to stay with the spirit of what people were doing before because habits have power over people and messing with them annoys people.
With the current change, they could have added a new tab that's highlighted when people go into the ledger so that everyone that goes there will want to check it out so people are aware of it.
Like a "new Features tab" that highlights and lets people easily access what has been changed or added rather then revamping the existing one to where you have people play guessing games as to how to get to what they used to access using the same commands.
To be clear,
I am nitpicking at this,
It's not game breaking what so ever ( for me ) (more of an annoyance to get used to) sense I figured out fairly fast that all I had to do was click 'next' to get to the screen i wanted when looking for manpower and force limit.
But to be fair, it was a random guess on my part when trying to find the screen i was looking for, because i knew it existed and i hoped that there was a easy way to get to it. I could not imagine that the Devs would make it that much harder to get to the manpower screen. I assume that most people would not assume this and just get mad.
But for the long run, IMO , whole thing needs to be made where we can find all the data that we need for each country by selecting it on the world map and picking an option rather then having to go to the ledger and sort though the damn thing to find the relevant data through different tabs that are annoying to navigate between.
You don't need to make all the data easily accessible ether as that can make for a bloated UI, but im assuming it would be easy to make it where you click on a country and are able to click on its flag, like you do to set it as a country of interest, and look up the data that is most relevant that players usually look at (manpower, force limit, total score, loans, treasury , income , Stability , Prestige , Tech , professionalism... etc. etc. ) .
