Revert back the fsx standards for views - F9, F10, F11, F13 - VC, 2d, External, Birds View down. (F10 could be alternate view to Pilots View)
Of topic (sorry for that!), but as a matter of fact that is easy enough already even with todays version:
Open the Aircraft.cfg of the AS A3X0 of your choice and look for the [Camera]-section (believe it's somewhere towards the end). In there there are four instances/camera's which have the addition 'HotKeySelect=', followed by the numbers 1 to 4 (the other multitude of cameras listed there don't have this addition). If you add "// " (without the quotation (") marks!) in front of the 'HotKeySelect'-line (e.g. '// HotKeySelect=..') these will be ignored next time when FSX reads the aircraft.cfg, giving you your default FSX views back under the F9 to F12 keys.
Had problems with EZdok camera's, but after doing the above all is working a breeze again!
Don't forget to first make a backup copy of the aircraft.cfg though should you want to revert back/things go wrong!
The above is basically how to do it. However i am presently not in a position to check to see if all is actually named ok (i am not at home now). Do hope however you get the idea.
Regarding the advanced version and what i would want to see in it: everything that matters to me has all been said already so (hopefully!) no use repeating things!
