Hello hasamba and thanks for these list.
There are software that aren't in the liberkey because there are other software that are better or equivalent : I think for example :
Recuva <==> PhotoRec .
There are also software that aren't in the liberkey because there are difficulties with license or author's permission for integration.
.
Have you verified if there aren't already proposed in the forum "Proposition de Logiciel" ?
For a better treatment we use some rules
http://www.liberkey.com/forum/propositions-de-logiciels/2170-propositions-de-logiciels.html.
Sorry this page is in french, (I've not already time for proposed a trad for the moment, I'm working for proposed an english help for the Liberkey on forum).
