TJ,
Be assured TiddlyWiki is extremely adaptable, rests on top of common
internet standards and technology HTML, CSS, Javascript (special
application there of) and more. It is both a front and backend, a friend
to coders and non coders alike and much more.
Responses below,
Regards
Tony

Understood and support your approach, however I could not understand it, I
just wanted a little more familiar language used.

I love chatting about the abstract, conceptual and nature of tiddlywiki,
and I can help you with this. I am no JS expert, others here are, But I
think what you are looking for is more than possible in TiddlyWiki, however
there are some conceptual differences from a Procedural or Object
programming language. I will try and dig up where I did a comprehensive
explanation of this difference.

If you build a solution where the tiddler titles can or need to change, but
they also represent a unique ID then yes this will break, but this is in
your hands. Not all reference mechanisms break, and less so if you use the
uni-links plugin and alias'e. A Few of us have a solution for strict unique
ids for some use cases. However using a changeable field (the Title) as a
unique or key field is of course not the way to do it, It is easy to use
other fields as the key field, not to mention datatiddlers Json formats and
custom lists.

Your Welcome, that was the intent. In learning tiddlywiki on TiddlyWiki.com
the "Filter Operators" and Widgets are the most likely areas you will find
answers, but search for other tiddlywiki resources because items such as
tobias'es solutions http://tobibeer.github.io/tb5/#Welcome and filter info
http://tobibeer.github.io/tw/filters/#Filter%20Examples are very helpful as
are other sites out there.
