As, presumably, the O-S version of Livecode will enable everyone to open stacks whether they are in the pre-2.7, the pre-5.5 or the post 5.5 format why doesn't RunRev (or someone authorised by them) release a small widget to open post 5.5 stacks and offer to save them in either the pre-2.7 or the pre-5.5 format right now?
