[TW5] selective per tiddler editor preview (5.1.11)

[wimm]

When you press show preview or hide preview in a Draft tiddler then this affects all open Draft tiddlers. When tiddler above the current tiddler expand the tiddler is moved out of view. If you only want the preview of the current tiddler to be switched on or off (TW5.1.11) the current tiddler stays in view.

Edit the $:/core/ui/EditTemplate/body tiddler. In bold the changes compared to the original tiddler.

How it works: When you press show preview it creates an extra field in the current tiddler called editpreview and fills it with the value "yes" . When you press hide preview this extra field is deleted. Only if the field value = "yes" the preview is shown. In this way it also remembers if you want to view the preview.
