 The ultimate point of my thesis is to provide a context-based replacement/enhancement for bash and zsh shell history.
 
 The idea is to:
-- Save each command with metadata (device, dir, gitdir, ...)
-- Recommend history based on saved metadata (e.g. it will be easier to get to commands specific to your project)
+- Save each command with metadata (device, directory, git, time, terminal session pid, ... see example below)
+- Recommend history based on saved metadata
+  - e.g. it will be easier to get to commands specific to the project you are currently working on (based on directory, git repository url, ...)
 - Provide a simple way to search whole history by command itself and/or metadata (e.g. imagine searching by project, directory, device, ...)
 - Synchronize history across devices 
 - Provide an API (to make the project easily extensible)
