-- Use WorkDir (raname to Workspace?) to shorten file names
 - Show what process/coroutines are running and allow to kill (active process buffer?)
 - Database idea: use special buffers to store information
     - Editing the buffer doesn't seem to be the slow part rather, accessing the data and putting it into the buffer (potentially hitting many different memory locations) I have a crazy idea to use buffers in order to store the names in a serialized format
