I would like to have a send to program button (or a dropdown) where I can send the scanned document. i.e. I choose the portable thunderbird in the settings by showing its path, when I click the button, the scanned document is sent to the program in the chosen format, pdf, jpg, etc. All of the programs I found that does this, try to find an installed mail program and gives error. They still dont know existence of portable email programs. :)
