[ From proton reddit announcement ]
Hey everyone,
Starting today, you will be able to see attachments displayed in the message list on Proton Mail for the web. This feature will come to mobile apps in the near future.
Attachment preview will help you find a document you need quickly and preview it in one click. You don’t need to open the email containing it to see the details of the document.
Please note that this is only available with the density set to “comfortable.” If you cannot see this improvement, you can check which interface density you’re using by clicking on the settings icon in your browser.
Yeah. I would’ve loved if it were optional / configurable .
