Truth be told, version 1.1.1 was initially only going to be released because I forgot to update a screenshot in version 1.1. But then I actually found a bug I needed to fix. 45th’s term ended in 2021, not 2020. That has been corrected. I also took the opportunity to add a couple more indicators. Now the symbols are:

! Impeached
!! Impeached twice
* Died in office
` Assassination attempted in office
`* Assassinated
\ Resigned from office
^ Not elected as POTUS this term
