This topic demonstrate a little project that I've been working on from time to time. The basic intent is to create a split-screen edit window that can be used for several purposes. (If you try out the demo links below, you can log in as user "TWikiGuest" and password "guest".
Sample uses:
Topic editing - Displays a TWiki topic in "view" mode in the top frame and "edit" view in the bottom frame. This is similar to the ideas discussed in TWiki:Codev.PreviewOnEditPage. Click here to see this in action. It allows you to see the effects of your edit immediately without having to switch back and forth from "preview." (Unformately, the "Reload Top Screen" isn't working yet because I haven't fully upgraded to Cairo.)
Discuss this topic - You could also use this as an interesting approach to adding comments to a topic. Click here to see a demo of this and comment on this topic.
Web commenting - This was my main motivation for undertaking this project, as discussed in TWiki:Codev.TWikiAsWebCommentaryTool. The basic idea is to be able to view simultaneously in one window any web page along with a TWiki topic in edit mode so I can make notes without having to switch back and forth between windows. Click here to see this demo. For this demo, the top frame will display TWiki:Codev.TWikiAsWebCommentaryTool and this topic in edit mode in the bottom frame. If you'd like to try it out on another web page of your own choosing, click here and follow the instructions provided.
