Feature suggestion: refactor the rewind/skip backward/forward buttons when playing a network stream, to be more user friendly

In versions 2 and 3 (windows), when clicking and holding the "previous media" button in the main window while playing a network stream such as an internet radio, the playback skips backwards (aka "rewinds").

There are several incoveniences with this:

1. Click-and-hold is not a widely used desktop OS mouse action (exception when doing it for drag and drop and safari back button on mac) nor a user pleasant experience

2. There is no control of precisely to jump backwards. You hold and... pray you hit the desired backwards time of playback

3. After holding the the skip forward button, the playback does not skip forward and instead it jumps to current live position of stream, and that after being stuck for several seconds not playing anything

4. There is no visual indication of how many seconds/minutes am I now backwards away from live time.

5. It doesn't work at all in the nightly dev version 4 (buttons are greyed out)

I presume the click and hold is only a hacky workaround to get the feature done; my perception is that the current implementation is far from being user friendly.

It would be tremendously useful to have a proper refactor of the UI, with a supplemental set of dedicated skip backwards/forward button and a visual indication of the backwards offset from "now" live stream time. Ideally a user setting would allow changing from a default of say 30 seconds per click to any other value.

Thanks
