Ok, this might just be a pretty big deal for fetching plugins or
bundles. I've only done some very quick tests but I'm so excited so I can't shut up:
Put a common iframe in a tiddler with the source set to your target TW. For example
<iframe src="
http://ooktech.com/jed/ExampleWikis/TiddlerSchools/" style="height:600px; width:600px;"/>
In viewmode you'll see - in this case - @Jeds "tiddler bundler" (initially called "schools"), but it could be e.g
tiddlywiki.com or any other site.
Now, as you may know you cannot drag a tiddler/plugin/bundle out of an iframe and drop it straight into your TW, for browser security reasons.
...BUT...
apparently you CAN drag the tiddler/plugin/bundle to the browser bookmark field and drop it there... and drop that bookmark straight into your TW!!!!!
This was news to, at least, me.
<:-)
P.S Things woudl be simplified if tiddlers had links with their own
titles to be dragged, intead of locating a title link elsewhere for the
tiddler. @Jeremy has mentioned introducing <$draggable> previously
and make titles draggable. Would fit well here. Actually, can't one
simply add a <a> around the title in the viewtemplate?
