Selective Clear cache (e.g. only podcasts)

Hi,

_Clear cache_ cleans too much by default IMO.

I don't mind keeping old text articles around, actually it's quite great. However, I only have 16GB on space on my phones, and no sd slot, so I cannot keep 4GB of podcasts.

Thus, it would be nice if _clear cache_ could discriminate between different types of data. Sort of like the [_Forget_ button in Firefox](https://support.mozilla.org/en-US/kb/clear-your-browsing-history-and-other-personal-dat)

Thanks,
Rasmus
