hi
please add Idx subtitle format support for new vers
thanks

I support this.
IDX/SUB format support, it's MUST-have - a lot of subtitles come in IDX+SUB format and Splash simply can't view them.(they take advantage of all options of Vsfilter/Directvobsub by Gabest)

This is planned to be added in future versions but do not know at the moment when will be available.
