Thanks for the feedback, I'll try to add instructions for the sh files and the python version. This is still very much a WIP so I'm not going to look into docker just yet.
For the highlighting, currently only a single email pattern input is supported. Type in your pattern into the box at the bottom, then click submit.
The pattern gets fed into a LIKE statement in SQLite, so just plaintext, with % representing a wildcard eg torvalds% would highlight files modified by an email starting with torvalds.
