I'm using MC for years now, for me it beats all others, even the expensive paid ones.
The one feature i miss is total commander's view text feature where you can scroll through files in one tab, and get to see the (text) contents in the other.
I wouldn't need it to do pics as well but since you already have that code in the multi viewer it could as well do it to, but it's not part of my request.
Thanks Mathias.
