Ticket Tracking

Does anybody have any recommendations for time tracking tools? Or even just all around PM tools (time tracking, internal/client communication, file sharing, issue tracking, analytics)?

The dilemma I'm currently facing is that we have one massive tool that we use now (LiquidPlanner). While it's awesome in many respects (one tool for everything minus invoicing), it is clunky and not good for ticket tracking and the comment ability is kind of lame (you can't search through messages! Srsly?!).
