A bit more basic, but I use two free desktop PC automation tools which I now can't do without.
1. TyperTask (https://typertask.en.uptodown.com/windows) to automate common tasks like adding different email signatures for different addresses etc etc.
2. ClipX (http://bluemars.org/clipx/) for managing a huge clipboard history file. This saves me SO much time it's unbelievable.
