[Plugin: Hana Code Insert] Hana mostly works but breaks some WP stuff

Hana’s primary functionality works, but the TinyMCE / WYSIWYG editor button is just there; it doesn’t do popup or do anything.

It does not work in Widgets.

It breaks WP’s auto-save and the post’s/page’s title-based link creator, although you can still manually click “Save Draft” or “Publish”.

This plugin is exactly what I want, but it’s breaking of autosave is too much risk–I’ve lost a couple posts in a short amount of time.

PLEASE update Hana for WP 3.0.1! Thanks!
