Absolutely stupid, completely unusable. Hasn't been updated and works with programs out of commission, so it just doesn't work. Video previews are completely unusable, timing captions is impossible, I'm screaming mad and ready to pull my hair out because this should be such a simple process and jubler has made it absolutely impossible while teasing me by looking like it's a functioning program. Internet garbage that should be forgotten until it's developers learn how to do anything.
