Automatic resizing for new lines is very suboptimal. Say you want your lines to be different widths? Like in a dialogue.

Another problem is that the sizes of the font are not displayed correctly (at least for some fonts).
Like if I select Helvetica 54 in the editor and in html5 it gives me something like Helvetica 48.
Thats makes aligning text objects a nightmare.
Considering C2 is an HTML5 engine, I don't know why it should be the case.
