[otrs] Question about "My Queue"

I've been searching the mailing list and google for the past few days. Someone has asked this question but never received an answer. So I'm trying to find out if the function of "My Queue" can actually serve a purpose and all tickets owned (aka created) by a user can appear in their "My Queue" this way it is easy which tickets you have taken as an agent from the raw queue. Also I was wondering if there is an option to not lock a ticket after it has been created/moved/edited etc, that it must be manually locked. Thanks, Any help is appreciated!!!
