I'm sorry I do not speak English. Google's translate.
1/ Simplification UI is not.
Unified ui. Reduction of awareness unit. + Play button Download button at the same time fast approaching.
Or swipe to the work of Play Download
2/ Flags of the color and location isnt would be awesome
3/ Quick access to the search
4/ Add new podcasts button better
If you waste your time, I'm sorry.
Thanks for a good app

I like the swiping described in 1) - just a slight swipe to the left could be "add to playlist", a slight swpie to the right could be "download episode".
