@lucid00 thanks for your tweet about polyglot HTML/ZIP/PNG files. It might be a useful technique for @TiddlyWiki so I wrote up a quick GH ticket:
Adopt ZIP format for storing tiddlers in TiddlyWiki HTML files · Issue #9410 · TiddlyWiki/TiddlyWiki5
The title of this ticket will most likely be meaningless without knowing that, surprisingly, it is possible to make a fully functional HTML file that is also a fully functional ZIP file – a so-call...
