Being able to participate to a giveaway directly from the list, without clicking on it first.

NO

I don't get what you're asking.

I think there's a browser plugin for this.

Like this?

When the list of games appear on the main site url "http://www.steamgifts.com/", I would like them green buttons right away ! :3

Oh, yes that would be unkind. Just asking, since the functionnality is available on tablets. Thanks for the answers and peace and love bros <3

Can I have a script that automatically enters all of the good giveaways for me? And trolls the forums for dropped keys and enters them as well?

Seeing the 2 giveaways you created you really should read stuff and not look for a way to skip more reading ;)
