i have been using LW for almost 2 yr, and i cant complain, belive me i can't live without LW right now.

i dont understand what you are asking for, but if i want more result in my search, i search again with just a right clik, thats easy.

certain size of file? what do you mean? that is possible, yes. only if you mean you want's result of a specific file size. go to tools option and find it your self, too easy. the default is any size, but you can change it to you specifications.
