Redmine

Hello,

We are trying to set up Redmine for one of our teams and they have no use for the subject line for their issue tracker and the existence of the subject field in the issues is a problem for them.

Ideally, we would like to be able to set the "required" settings so that the subject field can set to be required or not depending on the issue tracker. Identical to the way the custom fields are made and behave, but for non-custom fields as well (i.e. subject).

What I have tried is:
go into "field permissions" in workflow settings and set the "subject" field to "read-only" and this causes problems, especially at the creation of a new issue because the subject field is naturally "required" by Redmine and setting the "read-only" setting in "field permissions" just causes the subject field to disappear without any change in behavior; as in the subject field is still being "required" by the page/form but now there is no way to input it due to the "read-only" setting.

What I would like to know:
Where in Redmine's files or code does it reference the subject field's "required" property/flag?
I would like to find the "variable" or bit of code that is responsible for this and either set the subject field as "not required" or stop the code from looking for a valid entry in that field.

I was hoping that Redmine would keep this in the database like it does with the custom fields, but it seems like it doesn't.

Any assistance?
