I’m currently evaluating switching from Proton to Tuta and the experience has been pretty great so far. There are just a couple pain points/ questions I have before taking the plunge.

Recently, Proton recently released a calendar widget last week that has been very useful for me. Is there any change of Tuta calendar doing the same, or is this not possible to do securely?

I also use Simple Login for aliasing and have a hundreds of aliases. I know it’s possible to do the same in Tuta with custom domains, but are you also able to “pause” those aliases, or is it just create and delete? Curious as to what the management interface would be like

The calendar is integrated into the app and it also has its own app on mobile, which comes with an optional widget.

You can't pause aliases but you can disable and re-enable them. Tuta aliases are permanent, and you cannot delete them.
