Hi Shankar

Thanks for your questions,

1.  My long standing irritation, though a minor one, while using TiddlyWiki

It is possible for a Firefox extension to invoke system commands, as
illustrated in this venerable blog post:

However, I'm not sure that I'd be inclined to add the feature to TiddlyFox
itself, for fear that it turns into a ragbag of security holes. Instead, my
thinking is to keep TiddlyFox tightly focussed on enabling HTML/JS apps to
save changes to themselves.

That is correct, you just need an HTML5 compliant browser. The TiddlyWiki5
core code is somewhat tuned to take advantage of the new facilities of
HTML5, but TiddlyWiki classic still works fine on HTML5 browsers.

code is completely rewritten for flexibility and efficiency, and so old
plugins will not work. In fact, the wiki syntax itself is also not fully
compatible.

Best wishes
