I think it'd definitely be nice if someone wanted to update some of the templates and post it to the downloads section for other people to use/share, but it likely wouldn't be part of the core Qcodo release... mostly because SET and ENUM are both MySQL-specific constructs, and aren't really supported in other DB platforms.
The way Qcodo attempts to offer SET and ENUM-like functionality, but in a way that (we believe) is much more extensible as well as platform-independent is through the use of _type tables.
You can define a person_type table, and instead of having a ENUM column in your person table, you can simply have your person table FK to person_type, and achieve the same results:
person_type would have two columns: id and name.
person could have the following colums:
first_name VARCHAR
last_name VARCHAR
person_type_id UNSIGNED INT (FK's to person_type.id)
And lastly the person_type table would have the following values:
1 - Manager
2 - Director
3 - Employee
4 - HR
etc.
for SET support, you should be able to create a person_persontype_assn table that has:
person_id (which FKs to person.id)
person_type_id (which FKs to person_type.id)
And it should code generate the ability similar to SET. (haven't tested this out yet -- so if it doesn't work, let us know)
