No, I didn't go any further with it for this simple reason:
There were quite a few people who had been glittering on for a fair few years about how they wanted a
Metacard/Hypercard sort of front-end strapped on LiveCode. So I put a fair bit of effort into what you see here. This was met with a dull thud: not a single person responded or even encouraged me. So I thought
"@#$%^ them" and went and got on with things which served my needs rather than a bunch of people who talked about how they wanted things and when they got them said nothing.
No, of course it is not considered "done", see paragraph above.
Please "bogs" feel free, if it serves your needs (and, definitely don't do it for anybody else because . . . .)
to continue working with it and/or learn anything useful from what I have done.
