Occasionally, I download one or another file from compendiums that contain many dozens, even hundreds of files, often organized into multiple nested sub-directories, sometimes many levels deep. I wish you would implement even a limited search facility in the new-torrent pop-up, to help users select particular subsets of or individual files from among many in a single torrent. A regex search would be great, but even alphabetization starting from an arbitrary offset in the file names would be valuable. With this filtering, users would be able to much more easily select the particular files they wish to download, or easily specify those to which they wish to assign a given priority. Now, I'm usually forced to read each file name and many times individually make my on or off selections and download or seed priority specifications.
It seems a simple idea - I'm sure it's been considered. Thanks for your consideration to implement it.
