Jubler subtitle editor

I can't figure out how to use the software. It has so many options that i simply fumble around in it at the moment. Although the application is free source where is the manual ? It seems to be the video subtitle editor i want and want to learn but why do they not include a manual. I know that not many Mac users have a requirement for a manual but this application appears to be so powerful that a manual would go a long way to get a good start with a successful edit. If someone here can point me in the direction of a download for the manual thank you. I have tried to change the color of movie dialogue/text from the traditional white to use the color yellow. My brother has vision problems whereby white lettering is hard for him to see especially when the background is very pale or even white. However can't figure out how to change the color and if i do it does not stay colored .

The only reason for the low rating is because I can't figure out how to use the software. It has so many options and I can fumble around in it which shows me it's exactally the software I'm looking for. It has options and a pretty good look and feel to it with what looks like a well thought out user interface. I just feel like a stupid kid who's been put in the pilot seat of a 747 and told "it practically flys itself." A big red arrow pointing to the START button would go a LONG way.

Yes, this is a nicely working program!

(Mac version) Powerful, polished, and stable program with excellent help forum. Highly recommended.
