Great location, but also downsides

First of all I would like to join the previous speakers. On the whole a great system with great sound.
However, it has a few downsides:
example
-When there is seemingly no radio station search! Man must 0,05Mhz way through the entire range of 88,00Mhz to 108,00Mhz click = 400 clicks !!!
Setting the individual speaker volume levels is not implemented in radio mode only after the return to the main menu and re-enter the radio
-With SmartShare but you can (sometimes) to stream music and photos from a home PC) are there more menu items perform reproducible crash (freezing) of the software.
(Eg the icon offered "More" because I have never figured out what was there, actually come apart from the freezing of the software)
-Beautifully Would have been if I could assign the sound profiles the sources. So for example, in radio mode automatically always with Blueray 2.1 9.1. And if I could put Internet radio stations as preset button (wishful thinking ok, but at the price of the plant !?)
-no real adjustability of sound (Treble Bass Equalizer). While there is a point with a narrow-gauge USER equalizer, but that's a joke. Hardly effect.
- It is also not entirely clear where the high speakers belong, forward or backward? The color coding ends exactly at the loudspeakers because all connections are monochrome. In the manual, the speakers are shown only schematically. However, since there is the same system with 4x the small speakers it is probably ultimately matter. (Ok only in the technical data in the dimensions is the rear are smaller)
