Hi,
we have implemented freshservice as a tool for multi-department support. In our opinion there should be possibility for Requester to filter his tickets by support functions to which ticket is assigned to.
Example:
User opened HR ticket that will be open for next 90 days (on-going recruitment), after that he submitted another 30 IT tickets for different issues. Now when he wants to quickly find his HR ticket he has to scroll down and look for it.
With possibility to filter tickets in End User portal such problem won't occur.
