Hi, sorry to bother you about this very old project.
Despite its age, your DOM viewer is still the best-looking one out there and I was hoping to use it for teaching.
Unfortunately, the "Show Text Nodes" and "Show Indent Nodes" checkboxes do not seem to be working and ideally I would like to show my students a version with and without text nodes.
You are probably too busy with other things to look at this. I'm not very familiar with JavaScript, but I might be able to hack myself to a solution if you could point me into the right direction. Thanks!
