Quite naturally, I'm very interested in this type of projects. Unfortunately, your,
"Most who use English, do it unsuccessfully."
applies to yourself, and for a native speaking English writer, that's hard to beat.
Perhaps you should not write in 5 languages but in 3 only, like I do? It's all about preserving that at least your native language continues to sound right. (For the really gifted, even 10 tongues might not be a prob, but that's not us, obviously.)
Just my 2 cents.
As for AHK's ListView, there are some alternatives available within the AHK framework, written by excellent programmers. But then, I don't see the necessity for any list views here, it would all be about text processing by replace functions, and for this, heavy duty, AHK is not ideal to begin with. And then, translation tools have been on the market for a very long time now, and with astonishing little success, results-wise: So, before speaking of most income being given to charity, and before some programmer willing to script the needed function set for free, there should be some evidence why, all the more so with very little scripting work said to be necessary, the product would be able to surpass what sw houses with sometimes big manpower have tried to succeed in, more or less in vain.
Just my 2 cents, again.
