Ok, i have to admit. Having Pedro Castro as friend, make things easy to me, since he’s the creator of gnome-subtitles.
I’ve send him two patches for gnome-subtitles, the first one, was very easy, just to fix a dependence of libgstreamer-plugins-base. I just insert one single line on configure.in.
The second i had to work with glade and code some lines in many differente files, now, gnome-subtitles have a button to delete and insert lines in the main toolbar, and Pedro though that the search and substitute buttons should be removed from the toolbar, since people is more accustomed to use shortcut ctrl + f and ctrl + h. And gnome-subtitles was full of useless button in the main toolbar.
So, here is the actual version of gnome-subtitle:
gnome-subtitles
And here is the gnome-subtitles with patches
gnome-subtitles
I’m thinking contribute more and more for gnome-subtitles and perhaps in others gnome software.
Right now im talking with Pedro about other features to be included in the next version of gnome-subtitles.
That’s all for now 
By the way, gnome-subtitle is a very easy to learn project, and need YOUR help. Check the bug’s list and TODO list and help to improve this and other gnome software.
