The new UI for control assignments is a source of frustration, to put it mildly. To this day, I still haven’t really understood how to save a specific controller assignment for a specific aircraft in one of the three existing categories. Why three categories? Not only that, what is “keyboard transversal 2024”?. And you also may create a subcategory with its own name in each subcategory, which will increase the confusion (my confusion) to a maximum. And why then did an assignment I’ve saved disappears after restarting or changing the aircraft? You then sit helplessly in the cockpit and don’t know whether you want to start the procedure all over again. A description, or better yet, an Asobo video tutorial would be more than helpful to understand what the programmers were thinking. What is certain is that they had assumed that the universally acceptable controller UI of the FS 20 needs to be fundamentally rewritten. Wrong. As far as I know, there were no major complaints about the UI of FS 20.
There is a completely different way of how to design a controller UI, namely with a simple and clearly recognizable structure. For example, in the DCS flight simulation. There is only one (!) list for each aircraft with all possible controller assignments specific to the respective aircraft. These lists are for all existing input devices that the program has recognized and listed, keyboard, mouse, stick, throttle, pedals, digital or axis input, whatever is required. The assignment of a control function to an input device is absolutely clear in this way. And, in any new list for a new aircraft the program already has saved the most important assignments as “default”. So that in the simplest case you can start flying immediately with the most important controls. If you want to change individual functions, you can easily modify an assignment in the list. Double assignments are recognized and blocked. Fine-tuning of axis inputs or e.g. reversing the input command are of course available. This UI enables a simple and, above all, completely clear assignment of functions to all input devices.
I’ve understood this system from the very first moment. The new UI system of FS24 made me despair and is one of the main reasons why I stick with FS 20.
