Not only does it correct the 2004 SSE back to the OT (mostly) it also corrects some of the glaring errors in the original OT which the later versions should have corrected.
I am lucky to have had a wee tiny supporting role in this and I have seen some of the changes and they are amazing.
Nobody but the most hardened professional will see the wipe from the 2004 SSE to Editdroid OT mentioned in No 30. Even after it was explained to me, it was still tough to see as it is that good.
This is an edit not to be missed................
