Using Name Space
One hobby for me is using Tiddlywiki to develop tools for Tiddlywiki 
Assume an idea has come to your mind and you are going to implement it gradually. Example create a new table of content tool. Start with a simple name like new-toc
Create tiddlers like this
- new-toc/macros
- new-toc/styles
- new-toc/example
- new-toc/readme
Tags are very helpful, But They should be used with a plan and thought, if not your Tiddlywiki will be crowded with high entropy very soon.
Nonlinearity in Tiddlywiki is good but not intentionally! So, I use kookma Favorite plugin to put these in a folder, I can see all related tiddlers in one place.
NOTE: The idea comes from creating plugins in TiddlyWiki where a standard namespace is recommended.
