Is there a way (or a future plan) to enable/disable the list of mandatory default fields ? For example, I'd like to create a Tracker for remarks on documentation for example. The subject field is in most of the cases sufficient, description is an help but it is not mandatory to add any information. The same applies for an Action Tracker : sometimes precision on action is required, but most of the case it is not necessary.

thanx in advance
