I just installed extplorer.. and it is WONDERFUL!
If only... I could adjust the pop-up view window size either:
a) make the view area larger a typical letter-A2 format
b) or better- make it a user resizable!
Also - I did not see mention of this, but you may want to add to FAQs to use .htaccess parameters to deny access to protect private file folders.
It seems some of your users may not already know about .htaccess.
