There are times, when I am just leaving JD running on my computer, while I am not using it. Still, I am being asked for manually providing captchas for few hosters, and since I am not next to the computer, time is simply passing by. There should be an option, a button possibly, that when checked JD would not be asking for inputting manually captchas, just skipping to the next hoster/file. Now, if I am not mistaken, around 30s passes by on every link that requires manual captcha.

This will be an upcoming feature.
Until then you can reduce the wait time or even disable it in the settings (JAntiCaptcha).
