I managed to install the Wishlist v 0.5 on my test store, and it works fine. However, i have two little details to address:

First, the wishlist displays the previews at max size instead of a thumbnail. How and where do i change it so that it only shows a thumbnail?

Second, i can get the wishlist to appear if i add a new product to it, but i cannot find a way to access it from the main page, say, if a customer wants to check it on a second visit. Where to i change things to get it accessible?

And then, just for good measure, can you just list where to make changes for a French version of the button and the sidebox?

To see what i mean, my test store is here:
