Flank,
I can already see you contributing a lot to the community, thanks a lot. As
Jeremy says you may need to unlearn and relearn a little to get right into
tiddlywiki. I am myself intentionally a superuser, I do everything in the
world of wiki text etc... There is very little we can't do without
javascript except as Jeremy outlined. The key pieces are to me filters,
wiki text and the widgets (especially the list widget).
You may learn to ask the question "can I do it natively in tiddlywiki?" It
is mostly when you are brining in functions and API's you may need
Javascript otherwise not so often.
About learning tiddlywiki,
- Ask here in the forum (as you are doing)
- search tiddlywiki.com
