Request : ability to edit the "progress" value

[Zzzyyzzyxx]

Hello,

Here is a simple request for a feature that I was longing for long :
It would be nice to be able to edit the value of the progress column.
Something similar to "choose chapter ..." feature. (would be nice if it could be edited immediatly in the 'downloads' interface, if possible)

Mostly for E-hentai, when you try to download large library (2000 images)
and at some point, the download got interrupted,
just so you can restart the download at the exact image where there was a problem (without being forced to start all over again)

Right now, to get around this problem, I save a queue file, and I manually edit with notepad,
but it is quite cumbersome.
