Oddly, exactly 6 years after the last version, I've added a feature to
Ido Magal's TrashPlugin. Now the Delete button won't do anything on
Tiddlers tagged with dontDelete.
This is a great way to prevent critical Tiddlers (system, themes, css,
etc.) from getting accidentally wiped!
Enjoy,
David Szego

!Description
This plugin provides trash bin functionality. Instead of being
permanently removed, deleted tiddlers are tagged with Trash. Empty
the trash by clicking on the emptyTrash button in the [[Trash]]
tiddler. Holding down CTRL while clicking on delete will bypass the
trash.
!Installation instructions
Create a new tiddler in your wiki and copy the contents of this
tiddler into it. Name it the same and tag it with [[systemConfig]].
Save and reload your wiki.
!Uninstallation instructions
1. Empty the [[Trash]] ( emptyTrash )
2. Delete this tiddler.
