We didn't blushed you off. Till now we didn't receive any independent request to add this feature to N8. We did seek advice from our dealers but we didn't receive any support or request on this feature either. The most frequently requested new feature is song searching function which I have to admit, that's something N8 is lacking behind.
We did perform a technical feasibility study on your request. The function is pretty straight forward if N8 is Android based. The problem is, we don't have a "time" concept in N8 operation system. When you copy file into N8, we don't record the time of modification, we just copy the music file and analyze the ID3 tab. We didn't change the tag, and we don't have a specific way to record the time of copying. In other word, we need to add a clock feature, allow users to setup the clock, (we cannot assume user will enable WiFi and use network-provided time), and then we record the time of copying, and build the "recently added" playlist. The feature is not as straightforward as it appeared to be. Sorry for unable to fulfill your request.
