Well you see, if the work involved in actively developing external tools (or tools at all) would be trivial, I'm sure someone externally would've created some already (there's of course no real excuse for why there are no proper official ones).
There are atleast two motiviations to spend time and effort developing these: money or dedication to Graal, and I'm sure anyone dedicated enugh capable of finishing such a project has much better things to do than develop tools for free.
Robin, your misinformation or lack of knowledge does not put away the fact that a RC is more than a chat window
. Also don't blame Loriel, the fact that nothing's getting done on Gonstruct anymore is probably more my fault, there's no driving force anymore since I really don't care about Graal enugh anymore to put much free time into it. A hope might be that it's open source, which is not possible for a RC since a certain someone is pretty paranoid about his game's security (reasonably..).
