Security: forbid frames
Implement simple files viewer
Implement authorization (fix #2) and add anti-CSRF tokens
Use "&hellip;" instead of "…" - safe for windows-1251 and utf-8.
Forbid frames in old browsers too
Sync $_SESSION['changes:view'] with $FILES_ACCESS from config.php
Use DIRECTORY_SEPARATOR instead of hardcoded '/'
Allow view only files inside directories, listed in $DIRS
Switch from &nbsp; to pure white-space: pre;
No built-in mb_number_format() and mb_str_pad()...
Correct radiobuttons and checkboxes alignment
Set default password to 'changes' (w/o quotes), improvement for #2
