SimpleLogin seamless integration for email alias reverse-alias usage
SimpleLogin works very well with Proton Mail, and it's great that this is now included in certain paid subscriptions, however there are some opportunities for a more seamless integration in the Proton Mail apps (Web and Mobile), in particular:
Option to show actual email address as sender instead of reverse-alias under "From" (i.e. use "X-Simplelogin-Envelope-From" email header where enabled instead of "From").
Option to select email alias as sender under "From" (in the same way as "real" addresses/mailboxes) and then use actual email addresses (rather than the reverse-aliases) under "To", and have Proton Mail automatically use (and generate if not yet created) the reverse-alias addresses for each of the recipients.
Option to create a new alias from Proton Mail (i.e. under "Manage my addresses").
Essentially, the idea would be that when using the Proton Mail apps, one could use an email alias in exactly the same way as a "real" email address/mailbox, and have Proton Mail handle all the reverse-alias generation/substitution transparently to the end-user (at first glance, there would ideally still be some way of indicating that addresses have been substituted, perhaps with an icon next to the address that when clicked will show the reverse-alias that is actually used to send the email).
I have similar thoughts I shared in https://protonmail.uservoice.com/forums/284483-proton-mail/suggestions/47527166-offer-3-distinct-alias-types-seamlessly-from-proto regarding why I think Proton could offer a better aliasing offering all around with 3 distinct types of aliases.
With Simplelogin we can send emails from aliases. But It is so tired to open Simplelogin and create aliases and copy reverse aliases every time I send the mail. So just integrate Simplelogin aliases to Protonmail directly and make options to send via Simplelogin aliases directly in email sending page.
+ The options have to contain either sending from an existing ailases or create a new aliases.
Point 1 now seems to have been implemented somewhere between SimpleLogin and Proton Mail (I see in the headers that "From:" matches "X-Simplelogin-Original-From" containing the actual email address as sender, while "X-Pm-Original-From" has the reverse-alias) - thank you!
Point 2 next would be great - while responding to emails sent to an alias is simple enough, it's still a bit clunky to send a new email from an alias (need to look up the reverse-alias, and use the right mailbox to send from). Being able to select the alias as an email address under "From" when composing a message, then use the actual email addresses rather than having to look up reverse-aliases, would make using an alias as easy as a "real" email address/mailbox, and be a great selling point for Proton Mail / SimpleLogin as a package.

Just came here to post the same feature request, I'll add my vote to yours
Unsure what point 1 means, but I am here for points 2 and 3.
