Please audio recordings need some basically feature to be implemented, otherwise their use is almost impossible.
1 first of all, there is no point in showing in the time bar all recordings at the same time. Just show the corrent track, otherwise it is almost impossible to navigate to a specific point
2 It is equally important to have the possibility to rename the recordings. It is so difficult find the right records just from the order or the date

these 2 are the critical iussues. Other good feature may be add the possibility to export audio files, change the playback speed, edit the recordings (i.e. have the possibility to split a recording in two parts or unify 2 recordings in just one).

But please, the first two are critical. (sorry for eventual grammar errors)
