First of all, I think Precision X 16 / 5.2.0 is MUCH better than 5.0.0 and 5.1, which wouldn't even let BF4 load! However, I did find some limitations or possibly bugs in 5.2.0., but I wasn't sure what they were and whether I should post them in the official BUGS thread or make a new thread about it.
 
1. OSD does not show up in many games and instances... I created a toggle hotkey, which does work and it does turn on and turn off the OSD dot (above Start Up and Graph dots, under TEST in main Precision X UI Screen). Is it application dependent or is it just not working for other people also? I remember it working in games, in which it no longer works. I wanted OSD in BF4, for example, but I can't get it to show up!
2. Fan profiling is not working. There is no way to save your custom fan profile because as soon as I select Quiet, my custom profile resets itself to Quiet. That means I have to re-create custom fan profile each time I switch to Quiet profile. I don't know if the same thing happens when I select Aggressive profile. There should be a way to actually SAVE custom fan profile or multiple custom fan profiles instead of having just one CUSTOM selection that resets itself.
3. Precision X Server icon in taskbar notification appears 2 times or runs 2 instances unless I close them manually. There's got to be a way to prevent multiple instances and options to disable the icon. Precision X main UI screen/menu should just have a Server button that would enable or disable that icon. 
 
Please let me know if there are any work-arounds for these issues and/or when they will be fixed! I think a Precision X 16 5.2.1 Hotfix is needed!
 
The following are just preference ideas:
- There is no way to adjust OSD position, fonts, etc! It should at least allow you to pick font size and 4 corners. It would be best if we were presented with empty screen model in OSD setup/settings menu that would allow us to drag the OSD position anywhere we wanted. Having a choice between horizontal bar instead of vertical listing would also be awesome.
- OSD could look nicer, in a neat rectangle, smaller font with font color selection, etc.
