Good idea but the app should be improved

I liked this application: good design, several smart features, especially pause speed ups. But there are also several bugs made me to switch back to standard podcasts:
- voice boost do not works good: boosting underlying music also
- some podcasts began to download all episodes
- no plus-minus n-second control on the main screen
- episode progress bar is too far in the top of the screen
