Here are some TW5 customization I am working on to make it easier to create and modify tables built upon the content of other tiddlers.
The wiki URL is: http://mauloop.github.io/tw5-table-tool The GitHub repository is: https://github.com/mauloop/tw5-table-tool
This site is built as a Github page, thanks to the precious work of danielo515. Everything related to hosting TW5 on GitHub and Travis CI integration is well explained there.
If you are interested in TW5 itself, go to the Tiddlywiki home page.
