An experimental plugin provides TiddlyWiki with a Web Application SHell.

Follow up:

Although it's an early prototype based on the WASH-SE post, I think it shows some promise. Currently, the plugin provides:

• access to tiddlers as if they were microfiles
• TiddlyWiki users with the ability to create & edit persistent WASH commands

Over the next little while I'll be hacking away at this and try to build up a repository of useful little commands. open [tiddler name] and edit [tiddler name] are the first two I'll be looking at to show further the combined capabilities of TiddlyWiki and WASH.

In a week or two I'll move on and start building towards a more complete version of WASH for the Atomic OS project.
