I have being studying for other Methods to use here and starting to understand what is possible in talk.tiddlywiki. It is quite broad, and underused.
I would see value in developing a proper tiddlywiki markdown standard and adding it to those available in pandoc because if we do this once we then allow for
(← = conversion from; → = conversion to; ↔︎ = conversion from and to)
All pandoc available forms become usable.
Note the Wiki section?, TiddlyWiki is not there;
Wiki markup formats on Pandoc
↔︎ MediaWiki markup
↔︎ DokuWiki markup
← TikiWiki markup
← TWiki markup
← Vimwiki markup
→ XWiki markup
→ ZimWiki markup
↔︎ Jira wiki markup
← Creole
We could also build an online converter ourselves in a plugin for between markdown and TiddlyWIki markdown at a minimum.
