Before I give up and use something like Jira, I was wondering if anyone uses SDP to track feature requests and bugs in software applications?

In particular, we have a very active implementation of Dynamics CRM which (especially at the moment) has a very long list of bugs and improvements that need to be tracked.  the problem with SDP and this kind of work is that it all gets in the way of regular SDP tickets.  these are items that will sit unattended for a long time.

Is SDP suited to this, what is a typical use case?  Am I best using something like Jira for these?

Thanks
