Would be nice if font size changed by control+scrolling mouse wheel, most code editors do that. I can't imagine really needing (or wanting) to evaluate things in realtime (like the videos demonstrate) unless I was writing cryptic, mind-numbing algorithms all day every day. I like the idea in one of your videos, every function can have its own little window, but I wouldn't want that to create new files for me automatically in the background and it would have to be more useful than a straightforward "split window" editor function, which is already something I rarely use. The colors are cool but not as cool as my hacked Crunchbang+Geany colors. Maybe one day Light Table will be like a more graphical, user-friendly Emacs? I don't know. The videos are really eye-catching but realistically I can't imagine why I'd use Light Table. I realize there's already a lot of interest in this, but I would like to see more videos showing how this is actually more useful than Gedit or whatever.
