README block_quickstructure v2.0

Quickstructure is a moodle 2 block that allows course editors to quickly format
a course with coloured section title strips and thumbnails.
We've found these helpful to give students visual clues of the course structure.

In addition, the strips and thumbnails can be automatically used to form a top level
menu - an easy and visually appealing method of avoiding the infamous moodle SOD
('scroll-of-death').

Installation

Installation is complicated by the need to install a moodle form 'widget'
for a popup colour picker.

• • Colour Picker
    The colour picker popup widget - requires two changes to the source
    oustide of the block

#1. Put provided copies of
lib/form/colourpopup.php
lib/form/colourpopup.js
into your lib/form directory

#2. Patch lib/formslib.php [currently starting line 2351] to add the colourpopup element
