I think performance was one side of it, but the other one was manpower as well (I wasn't around at that time, so I may
be wrong...). Now it would surely be manpower, given we are just 4-5 developers in total, often not all present for some
time due to personal work/life commitments. So I think that for the time being, TDE will remain on TQt3, unless Tim
comes around and has other ideas about it (given that he is the project coordinator after all).
