first of all: as far as i can see you're plugin works fine now - awesome work and a big THANKS for sharing this to us!!!
Two more (little) things to ask:
1.) Product caching
The Loadtime of a page using you're plugin is very high (sth. between 5 to 10 seconds), cause it seems all category products get cached. My categories have about 100 to 150 products. Is there any possibility to make that faster?
2.) Price Style
I would like to change the style of the price (bigger and strong), but if i try to change it, the whole page font changes. Is it possible to change only the style of the price?
Thanks a lot!
