Could you maybe try and make it compatible with SumRndmDde's ShakingText Plugin?

Hello! I've tried SRD Shaking Text Plugin and it will show the custom colors if my Plugin is above in the plugins manager. The only part that doesn't work is the gradient colors, SRD plugin will only show the second color of the gradient. This can't be fixed within my Plugin. Changes has to be made in SRD Plugin so it can call my plugin functions to use gradient colors.
