Many ProtonMail users handle a high volume of emails every day and often need small productivity tools to speed up their work. A built-in panel offering simple utilities like quick text formatting, a snippet creator, a link checker, and an email content helper could make daily communication much faster and easier.
I’ve created an external toolbox at https://toolinq.com
that provides similar utilities. If ProtonMail adds a simplified version of these features directly inside the inbox, it could make the overall user experience even more efficient.
