I think that It's better post all the questions in this thread because everybody can learn. At the same time we are building a 'Database' where we can check the info when we have doubts flying this monster of the skies.
I'll post a few updated answers to questions, but I didn't want to continaully push this to the top as I'm sure it's a bother to others here who aren't interested in this addon.
In any case, one user had some difficulties getting the fuel balancing automation system to work (which impacts the center of gravity) but they are on Win10, so I don't know if that makes a difference. I have not encountered those difficulties but am still trying to investigate.
Another use had difficulties experiencing uncontrolled view panning in the VC, as well as mach tuck when exceeding Mach 1. As illustrated in post #6 at the beginning of this thread, there is a file update that mitigates the Mach 1 issue. Regarding the view panning, one must disable their joystick hardware in FSX itself, and use the addon's included joystick/hardware utility.
I attempted to send the following (in part) to one of the users:
I recommend carefully reading from that big Tu-144 thread I made a few months (year?) ago here at SOH, as I have provided links to a few patches in there that correct the nose dip behavior when going over Mach 1, and I specifically reference it in the thread. Most direction is in post #6 in the thread:

In additional to this, I also recommend being sure to make use of trim, and ensuring that the aircraft's canards as well as nose are up/retracted prior to going Mach 1.
Additionally, you need to do the following to set up the joystick properly:
1. Disable your joystick/controls in FSX. I think there's a checkbox in the controls settings that does it universally.
2. Load the aircraft in 2D panel mode. (Should be a setting with FSX to load aircraft in 2D mode).
3. Following the attached PDF guidance to select the proper controls and map them to your hardware. This takes a few tries as the tool isn't very friendly, but I provided links earlier with further detail on how to use it.
4. Upon completion, you should have a fully mapped Tu-144. Remember, it has its own joystick utility, and trying to use hardware that is activated in FSX itself will lead to problems like the view panning issue.
5. When loading the aircraft in future sessions, you still need to ensure that you load in 2D first, with the joystick disabled. After the aircraft initially loads in the sim, I'll usually flick the hat-switch on my joystick left or right to "wake up" the aircraft's joystick logic so it starts reading my hardware for this session. Following that, I'll right click on an open spot out of the windows in 2D mode and switch to the VC for the remainder of the flight. Keep in mind that some functions such as the engineer's panel are only available in 2D mode.
