Yess!!!
Thanks for sticking with this 
That’s a cool trick to know. I don’t really make assumptions about how TB export works, I just try stuff that could maybe work. This is another thing to try
I do appreciate the background on some of these things. Though I don’t fault Eastgate for the export stuff being a bit… peculiar at times 
I am amazed at both how cool Tinderbox is, and how long Eastgate’s been doing it, how the software has evolved.
Yep, I asked for $HTMLLinkExtension… I don’t know if anyone else asked, but I’m glad he added it. Previously I had been doing all link substitution using $HTMLExportCommand to call an outside program and that was slooooow.
The one thing that I DESPERATELY want him to add is to bring back copying & pasting text links. I’ve got a website built from Tinderbox that has 94 content pages right now, and I’m always planning to add more… and I love using text links – but it’s a giant PITA to move text that has text links in it now. If Eastgate brings back this functionality, that will remove the last major obstacle to TB being an absolutely killer website construction platform (for me).
