Redmine

issue should be renamed to "Allow to disable feature attachment"
I don't have permission for that

We will have new custom field format "File" in Redmine 3.4.0 (#6719). It would be great if we can disable default "Files" field by tracker like #25052.

We can configure to show specific field name (e.g. "Screenshot", "Error log", "Patch" ...) instead of generic "Files" if this feature is implemented.

I investigated, but I abandoned it.
I did the following things.

1. Add attachment to tracker.

2. Hide the attachmented file area of [issues/new] and [issues/edit].

• Reflects "read only" and "required" to attached files..
• Disable drag & drop of attached files.
