After seeing words "very experimental", I'm willing to share some ideas, maybe too controversial otherwise for suckless folk ;)
First of all, check Recdit[1] editor. It's Mac OS X app, but nice paper and short video is available. It has some unique features. Is vertical side by side layout stupid idea? Maybe not. We've gone from small screens to high resolution widescreen monitors. Moreover 2 or 3-screens setup isn't fancy anymore. Using so much vertical space effectively for text editing is a topic worth of consideration. Version control systems have evolved past few years. Still more fine-grained history could be useful sometimes. Recdit introduced deep diffs. Also this could be used as argument for avoiding syntax highlighting (too much colors at once). I love the text editor Sam. There is one problem with it - it's stack based WM over stack based WM. How to resolve this issue? Just look at so called distraction-free editors like FocusWriter[2] - using full screen is a feature. Maybe those group of editors is silly, but at least they don't pretend to be anything else than text editors. I think that they were created as response to complex WYSIWYG editors and IDE's, which made religion out of interface. Sam power with more classical interface (tabs - just check how FocusWriter uses them) and Quake-like console (showing when needed) for regexps could be a quite useful combo. It looks like I presented idea for pretty much full blown text editor, now bring in some bashing ;) [1] http://www.thimbleby.net/truetext/ [2] http://gottcode.org/focuswriter/ -- Paul Onyschuk
