I’m looking for a youtube client that can conveniently “store” and switch between YT channels. Specifically, I’m looking for something that I can use to tailor my YT algorithm and feed by creating new accounts for different interests and purposes (one for tech, another for gaming, one for each varied hobby I’m interested in, etc.). The privacy benefits of such a system are of course obvious.

I guess to itemize the requirements:

1. Runs on Mint
2. Convenient for normal use
3. Switch between YT accounts easily
4. FOSS if at all possible

I have found custom YT clients already, however as far as I can tell none of these suit my purposes (mostly seem to advertise anonymity and commenting/subscribing without a YT account)
