Great points, thanks.
Can you clarify what you mean by “local decryption”? I thought Proton and Tuta work pretty much the same way, but perhaps there’s a distinction I’m missing.
One thing I like about Tuta is that it has the option to cache your messages in localstorage in your browser so you can do full-text search. FWIW, I think Proton added a similar feature recently, though I have not tried it. I imagine neither would work very well with large mailboxes; probably better to configure a real email client.
Related feature on my wish list: I’d love a way to basically fork a feed based on regex pattern matching. This would be useful for some premium feeds that lump multiple podcasts together. For example, one of my Patreon feeds includes three shows: the ad-free main feed, the first-tier weekly premium feed, and the second-tier monthly premium feed.
I don’t want to filter them out because I DO want to listen to all of them, but for organizational purposes I don’t want them lumped together. I’d prefer to display these as two or three separate podcasts in my display.
Another example is the Maximum Fun premium BoCo feed. They include the bonus content for ALL their shows (which is…a lot) in a single feed. I only listen to about half a dozen, and even that is a bit of a mess in one feed!
