I want to make some interesting tool to handle email accounts. So I need some ideas. From your point of view, what do you need in your email account so that I can facilitate you.
You can give ideas related to visualization, intelligence etc .
Email should feel more like you are having a conversation and less like you are sending a physical letter back and forth. So instead of opening the email application and seeing a list of your most recent received emails, you should see the last conversation you had before closing the application. This could prevent problems such as when you believe you have already sent something and find out days later that it was saved as a draft and never made it through.
