I have been ripping hairs out of my head on this issue several times.
Its all a part of the game i guess The "group model and fill with red color" trick has been a great help to me.

My models

I think i will give the TimeTrack a go. Thanks ppl!

Does anyone know if there is a plugin for taking the time you have used on a model? I mean, how long did you use on any given model? Have searched, but i have not found anything so far.
