@jeremyruston I really like the share site and I wrote the following bookmarklet to make it easy to convert tiddler.json links. I’m glad you are promoting it, maybe the bookmarklet will become less necessary:
For @TW_Tones issue, I don’t think the issue duplicates at the prerelease share site. The issue does happen at the main prerelease site. Looking at the DOM of the misbehaving edit widget content, the codemirror plugin is my first suspicion. @TW_Tones I suggest downloading the prelease and disabling the codemirror plugin. If that makes the issue go away, then it will help narrow down the issue.
I am working on an html/javascript page which fetches a remote TW, prepends extra tiddlers, and loads the result in an iframe. The idea is to have the functionality of the share site available to any TW edition rather than just the (effectively) empty edition of the share site.
I’ll share more once I have a working prototype.
