Improve (ease) the category attribution to podcasts

How :

• by proposing to select a category when subscribing to a new podcast

• For example, by using Tinder swiping left and right mechanism while parsing the existing categories for a podcast

• by presenting all category with checkboxes when we want to select categories for a podcast

Why ?

Because I subscribe to A LOT of podcasts (but not automatically download the new episodes) and when I rarely have nothing to listen to, I usually browse a category I want and select an old unlistenned episode. But unfortunately my podcasts are either not categorized or categorized by categories from its RSS feed that don’t match mine. And I end up with lots of different but similar categories with one or two podcasts in them.
