How do I get the pop up to appear all the time? If I close it what option is there to select to bring it back up?
The only way to make it appear all the time within Gmail is to minimize it by clicking on the gray top bar of the plugin instead of the "X" icon.
If you close it with "X" you can then open it up either by clicking on the "TD Add" button to add an email as a task or reload the page with F5.
If you would prefer to have Todoist in your browser all the time even outside of Gmail and be able to also add websites as tasks, we recommend our browser plugins (for Chrome: https://todoist.com/chrome or Firefox: https://todoist.com/firefox ).
