Hi there!
When you mean add effects, you mean like add +3 to a custom parameter for example:
- <GrowC:paramId/shortName:value >
Unfortunately, this plugin does not cover the visual part. Maybe I will do it someday. But I'm pretty sure you can add it with plugins that can add gauges, like the Ultra Hud Maker or Galv Gauge variables. Because my plugin delivers to you a current and max value.
