@rcentros. Yep, emacs with a plugin like fountain-works looks like the way to go. Thanks for the recommendation and info. I must admit, I am writing more and more in ASCII these days. I am using notepad+ a lot in Windows. It's quite nice, has multi-tab, but finding the settings to change options is the stuff of tortured fever dreams. Is emacs multi-tab? And does it do colored fonts? I've never used it.
Edit: watched the video. Thanks for your trouble. Yeah, that's impressive. I see the plugin fountain-works is for script writing. Can it be adapted to a general writing format--i.e., can scriptwriting template be dropped? Crucially, does it support multi-tab? I am forever flipping between windows and editing. But emacs definately looks worth exploring. I wonder if it works under windows...
Edit: Okay, GNU Emacs works in windows. So it's a question of getting the plugins working. I'll have a play around with this at some point.
Edit: The Centaur plugin provides tabs. Not sure if you can mix and match with other plugins such as fountain-works. But yeah, definately an interesting option when I feel like looking around. Always on the lookout for an interesting editor. I actually managed to copy some of the power features to windows using auto hot key.
The base software does look kinda ugly (like a DOS program), but the Centaur plug-in sexes it up. Call me shallow, but I like shiny stuff where possible.
