I want to try adding some new database fields and other experimental changes... so I'm starting to study the code structure.
The SQL table creation seems like something a code generator is publishing. The migrations: https://gitlab.com/edgyemma/Postmill/tree/master/src/Migrations
is there some specific IDE that generates these? Are you using a drag/drop user interface or something? How do you edit/compile/run cycle when developing the PHP + database logic?
