Thanks to Geoff Longman the author of the Spindle plugin. Without Spindle there would be no Tapestry Palette. Geoff even helped out by modifying the Spindle editors to incorporate the text range highlighting code I developed for the palette drag and drop.

Alexey Romanchuk provided the code for manual jwcid assignment during drag and drop editing of templates.

Finally, thank you to the anonymous person who provided some of the palette tree-view icons.
