Perhaps you are right Manfred.
There are basic customization like shooting RAW, no sound on click, focus peaking yellow, and so forth, that could be used as a starting point for customization.
Of course, in a deeper customization other setting could be applied.
The advantage of this, could be changing informations about how experimenting and testing new customizations.
Example: I saw that there is a bunch of setting to shoot fireworks. An implemented setting could be of some use.
Well... may be it is not a good idea.
And you know Manfred... I hate - like many - to read and study the f** manual !
