Wordpress plugin Tweak to filter posts by custom taxonomies

We created taxonomies based on series of terms and we need a live filter posts through multiple custom taxonomies. We are already using this wordpress theme : [login to view URL] We have already started working, you can see the actual result here : [login to view URL] Important !!! Here is the result to obtain : [login to view URL] The plugin to hack is here : [login to view URL] FYI, we know that this plugin [login to view URL] uses custom taxonomies, and maybe its functionality could be mixed with the one we need to hack. The needs step by step : 1. add the custom taxonomies for the plugin to hack [login to view URL] (each custom taxonomy is automaticaly generating a new multiselect box) 2. replace the multiselect box "select multiple" element by inline checkboxes for all terms to have the same visual as the already selected terms on the right. Actualy, the selected terms are with a little cross "x" to deselect. We need a little "+" for the non selected terms on the left. 3. replace the button "FILTER" by directly apply the filter function on select each term. 4. one click to select on the left terms (as actual) and another click to deselect also on the left terms (actualy, we have to click on the right terms to deselect)... And of course delete the right terms. 5. render the post results as we provide the mockup. Title + featured image + some custom fields ... For the post results, if i'm in the category "locations"... So the post results must show only related post to "locations" before i select anything. In few words work is to add or replace these functions : - add the custom taxonomies ability ; - replace the "select multiple" by inline checkboxes ; - replace the function button and the right selected terms by direct selection/deselection - respect the mockup to have three aspect for each terms : unselected // selected // greyed or invisible (if no post is associated) ; - render the posts results as described on the mockup [login to view URL] To collaborate you are agree to use : - Google Wave to share and edit in real time all the ideas, documents and texts (we can send invitations)... - Google chat - the very good agile solution Scrumy for planification (we need to know how and when) : [login to view URL] Before you place your bid, you should know how you will tweak the plugin. I will ask you specific details and also some demo of your similar projects. Don't hesitate to ask us if you need more informations.
