Thank you giga,
sure,
i know css
but, although I change the margin, the arrow has not a good position, and, if i solve the position in the feeds, i have a new problem in the rest of menu
i’d like to switch the wrench.gif icon by each category
i’d like to modify the position of the arrow in the sidebar due to not oversee it on the text of menu if it’s longer than one line: for example the rss feeds.
