1) The DOM is hidden and never rendered, plain HTML will only be rendered if the user does not allow Javascript to execute.

2) Yeah the scene graph would tell the renderer to only render the bare minimum with a clipping rectangle. Re-rendering the whole canvas is only done when some sort of "global" change like scrolling occurs.

3) I agree with you completely on this one. There are ways to do it for sure but they require some tinkering. Like I said in another reply, one of the main goals is to keep everything consistent. And actually, with the newer browsers the text rendering has actually been really good canvas.

4) For the set of questions with hotkeys, I do not intend to remove any functionality from end user. I never really thought about these things so thanks a lot, now I can keep them in mind. I cannot give you a specific answer as of right now, but I do know there are ways of capturing text selection and keeping that selection independent from how the user tries to highlight text.

I don't find any of this negative, on the contrary I am thankful for the feedback.
