This was kind of asked for in
https://www.altbinz.net/forum/help-5/option-not-to-show-password-protected-archives-in-binsearch-tab/, but I'd like to see a toggle button like "Collections" or "NFO" which filters out all passworded posts. Presently there is a (*) to the left edge, but this doesn't appear to show up as a part of the text search filter - if you set it to remove all "(*)"s, it doesn't do anything. I realise that the Collections and NFO buttons are filtered server-side, but a client-side (if need be) toggle for this would be great.
The data is clearly there, and it should be trivial to implement.
