NOTE: i've just added the following strings to the en-GB.mod_rokuserchart.ini lang file:
MC_RUC_WIDTH="Width of Chart"
MC_RUC_WIDTH_DESC="The chart width specified in px"
MC_RUC_HEIGHT="Height of Chart"
MC_RUC_HEIGHT_DESC="The chart height specified in px"
If you have done a translation already, please provide the translations for these new strings. Cheers!
