Love the product but you really really need to address that search performance. Using the webbrowser or windows app and searching for a word in the top search field, like "developer" it takes 4.5 sec(!!) to get the link named "developer garden".

Of course it might need to do some online stuff as well but please show the simplest result asap (=instantly), searching the titles should be done while typing the word I think.. when I have pressed "dev.." it should already have all matching titles in the result.
