Nav speed + progress bar ??!

Thank you so much to update release better than marantz !!! Please can you release a version with modifiable progress bar when playing a song ?? And with marantz the navigation in net/USB is not "smooth" as the marantz official app that is really fast for navigation (quite instantaneous)

So please
1-navigation speed, like marantz app
2-Changing possible playing progress bar
