IMO it's misleading to call it an email client when it does not do actual email. Making your Gmail client also-an-Outlook-client does not make it an email client.
I have a fairly non standard use of email, so I'm a bad target for brain picking. I can give a summary, though.
I work generally using a simplified GTD. Important features which I already have are good integration with my calendar and todoist as well as keyboard only navigation. Email analysis features I'd like to have are classification of:
- messages where my action is required;
- message classification by project;
- how long will it take me to handle this message (i.e. do it now vs add to todoist)
