If you have the interest and skills you are welcome to edit the TiddlyWeb datastore by hand. The tools you will need to do so depend on the store you are using.

The text store that ships with TiddlyWeb is a collection of UTF-8 encoded files in a directory hierarchy. Their format should be relatively straightforward.

If you choose to edit the datastore by hand you should be aware that this is quite likely to result in unpredictable HTTP caching behavior as revisions ids, modified times and the like are used for generating ETags.
