Thanks for working on this Antony! :)

I have been testing this out for a few weeks and I really think it is an 
definite improvement to the current Blender baking/exporting workflow 
for game artists.
Low poly meshes should always be triangulated pre-normal map bake and 
retain the same triangulation when exported, and the modifier allows 
this to be done non-destructively while still allowing the user to 
visualise the triangulation result on the mesh without manual triangulation.

Manually triangulating as mesh works ok, but has limitations such as 
converting a triangulated mesh back to quads does not always revert back 
to the original topology that was present pre-triangulation.
When baking with an all quad mesh, the triangulation that is done 
internally in Morten's TS might not match the manual triangulation that 
the user applies on export, which potentially could cause issues because 
the normal map would be compensating for faces that no longer exist, 
which would give an incorrect result.

All in all I think this will be a very valuable modifier to have and 
would save lots of time.
