well, so far, s&r works great ! i'm SO happy to have it ! i've not tried any regular expressions yet but this could be the motivation i need to learn how to use those.
just one tiny suggestion : would it be possible to have a message saying that we've reached the end of the document, and asking if we should continue searching from the beginning ? just now i did a search for some tags which i could only replace *sometimes*, i did search one by one instead of doing "replace all", and i noticed that if you're not paying attention you can easily just keep going around and around forever like that...
