Fix for DLTP-9 and partial work on DLTP-51 (format white space and add links to text on abstract text on show page).
Unused method argument - `resource`. If it's necessary, use `_` or `_resource` as an argument name to indicate that it won't be used. You can also write as `after_sign_in_path_for(*)` if you want the method to accept any arguments but don't care about them.
