This is a fantastic mod to which I have started a branch as this should really be in the core of the system.
So far I have the following: -
Time Spent added to the ticket, and continually adds up
Ability to add time via internal post and reply to client
Use Custom List to hold ticket time type
Display Total time in ticket information at top
Display ticket time and time type in thread header
Even though I have got all this working I do currently have a little bug which is that for some reason the ticket time and type is not saving to the threat.
Will keep you all updated though, and any help is welcome!
