You kind kind of filter in FTP File View, but it's not as simple as just hitting CTRL-F. To filter right-click on the column you want to filter and then click "Filter Editor..."
Thanks for the feedback! I have implemented the functionality in the next major version (V6).

It would be handy if the popup in the file-panel or a CTRL-F keystroke would give an option to filter files, so that you can easily find files / limit the view to that filter.
