Personally, it took me way too long to find the pleasures of Saved searches and I think many developers could be more efficient and would sooner jump on tickets, if they had easily accessible lists/reports. These should be available to all registered bugzilla users, just from the left sidebar.
Ticket assignment, is one of the areas where the default setup of Mantis is much more transparent for instance and though I'm no real fan of Mantis, I have to say this is where the default setup of bugzilla really needs some improvement.
I'm thinking of the following default searches/reports:
"Today" - list of all bugs with changes in the past 24 hours (open and closed)
"Assigned to me" - (only open bugs)
"Reported by me" - (only open bugs)
"Related to me" - where you are either on CC, reporter or assigned or where you commented. (open only).
Other suggestions for defaults are welcome.
