Many times, we would like to add a note onto each of our Mails, for future reference or action. This needs to be done without disturbing the original mail, but available every time you view that mail. Just like sticky notes for GMail!
Just install the extension Simple GMail Notes (available for both Chrome & Firefox). Once installed, you can write brief notes for each of your mail threads on GMail. This extension is 100% free and open source. Your notes are stored on your own Google Drive. You can write any text in your notes, give them different colours and even add your notes to your Calendar.
This simple utility gives you immense power to put Sticky Notes or Post-Its to each of your email threads – get more productive!
