* Changed headings under Content
Made them H2 and changed the wording a bit.
* Move the list of filters to another tiddler
There is a tiddler for Extended Listops Filters, and the list should go there, so that the Widget tiddler does not get too overcrowded.
* Rework comparison to ActionSetFieldWidget
* Add notes on de-duplication
* Update link to Extended Listops Filters
* Updated link to Extended Listops Filters
* Update link to Extended Listops Filters
Duh. This was the most important one.
* Remove repeated links to widgets within one section
* Re-create original tiddler with a redirect notice
* Excised the examples into a separate tiddler
Also created an "examples" subdirectory under tw5.com/tiddlers/widgets.
* Clarify the drag-n-drop behaviour
In my case I misunderstood it: I thought that I need to select the text and
drag the selection, because drag-n-drop did not work by default.
* Fix grammar
* House style:
** Spaces after the "!" of titles
** Blank line after titles
** Sentence Case for Heading Text
* Make use of wikitext-example-without-html macro for the examples
* Make use of .tip macro for tip
* Some phrasing improvements and clarifications
