Maybe I'm just missing something here, but:

Please make it possible to use a filter for the files scanned using Find in project. I almost always have a situation where I'm searching for something in my HTML files only and that something will be present in almost all of the PHP files, thus adding a lot of noise to the search result dialog.

There will also be situations where I'm searching for instance all index.php files in a large project.

And while I'm at it, please make the Find in project faster ;^)
