Hi Arkady

Thanks for the encouragement, and the detailed feedback, much appreciated.

Great, I'm glad that the checkbox and list widgets are understandable.

Not yet. TW5 doesn't yet really have the general concept of programmable
actions, but something along those lines is going to be useful. For the
moment, I'd expect a GxD implementation to have it's own extended checkbox
widget.

"tiddlerfield" modules. The core tiddlerfields are in boot.js:

each type of view that you need would be a separate ViewTemplate segment
(i.e. a tiddler tagged $:/tags/ViewTemplate). You'd wrap it in a reveal
widget that would selectively display the template depending on the tags on
the current tiddler. The reveal widget doesn't yet allow for testing tags,
though.

The plan is to extend the tw-new-tiddler message so that the title of a
template tiddler can be provided.

No, there's no GTD implementations that I'm aware of.

Do be aware that TW5 will undergo quite significant changes in the next
couple of days as I complete a round of refactoring that I've been doing.
With the new changes the generated HTML is much cleaner, and the individual
widgets have been rationalised and simplified:

Thank you, much appreciated. Eventually we'll minify the TW5 core by
default, which should reduce the footprint somewhat!

Best wishes

Jeremy
