Download shows to listen offline, please!

With this app I either need to be on wi-fi or have a cell connection (ie. uses data). Why cant we download shows as podcasts to listen to later? Id love to be able to download shows on wi-fi to listen to while Im driving or working in the yard, but instead if I want to listen on the go I have to have a good connection and use my data. Also, the player needs buttons to skip ahead or back 15 sec like the iPhones native podcast player has.
