Add thematic filters to content to navigate the application

Hello, first of all thank you. Nice application.

I have a few points to submit to improve the application.

-Filter. It would be interesting to be able to hide what we're not interested in at the moment, in order to have a clearer application.

-Favorites. It would be interesting to be able to choose favorites above our own daily routine. Or a module like "Sleep" or "Meditation" where you can find your favorites in each category.

What's more, it would be interesting to have a new "sos"-style category for those who are starting to have an anxiety attack or the beginning of an anxious face, with exercises to guide us, because it's very difficult to do the breathing alone. Or even open-eye meditation, inviting us to walk to relax while meditating (a bit like headspace).
