I believe it would be easier to "pin" languages when searching. For example, I am searching for English and French podcasts, but if I want to search in French, I uncheck English. Later, if I want podcasts to shown in two langauges, I have to search for this language again. With two languages it's manageable, but with 3+ it starts to be hard. My suggestion is pinning desired languages to the top of language list so that checking/unchecking is easier, or creating a list of languages preferred that would always appear on top of search list. Thanks a lot.
