Mike, nice module, perfect solution. One question I have relating to this and another module (layered navigation module), and maybe I have missed something here, but these are both excellent additions to the standard prestashop theme however it took me quite a while to track them down and there were a number of similar paid options. Are these modules that are being developed for 1.5 and you have just brought them forward here or are they being done as standalone modules?
I am pretty happy with prestashop, but I do tend to spend a lot of time searching for some core fundamental additions such as the ones above which appear to be "ready to go"
Cheers and thanks for the help
