Firstly, i'd like to thank LAMPB for his Clear Cart mod, thanks to his mod, I worked out how to implement this correctly, I've also used your text layout!
What does this contribution do?
This contribution adds a "Remove Product" button (the familiar rubbish bin) that once clicked removes the selected product from the cart. It looks far more professional then the 'click the checkbox then press the update button' route.
Its very easy to install, just edit some lines on a few files and off you go. To see this in action have a look at this site that is being work on: http://www.theadvancedskincareclinic.com/index_.php
please note: this is still in testing phase hence the main file is index_.php and not index.php. Feel free to provide feedback or any comments!
