Feature: Choose color for outline of subtitles

[G|ga]

Really small feature request. If i choose "Use outline font" for subtitles, i can't choose the color of the outline, it's always black. Would be nice if there would be the possibility to change the color of the outline, especially if i want the font-color to be black or another dark color. Same counts for the shadow if i choose "Use 'shadow' effect for subtitles'".

Just wanted to bump this thread, because i really would like to see that feature.
I don't think it is a big deal to implement it, because there's already an outline in black available. The "only" thing that has to be added is the possibility to choose a different color for the outline.
Thanks in advance.
