I'm trying to make an effect in openshot for lift-gamma-gain based colorgrading. I downloaded the latest Movit library and put it on the rigth plaece, MLT and Frei0r is installed and openshot is too. Now i got an XML file (based on these instructions) that looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE openshot-effect>
<effect>
<title translatable="True">Color adjustment</title>
<description translatable="True">Simple color adjustment</description>
<icon>coloradj_RGB.png</icon>

<service>movit.lift_gamma_gain</service>
<param name="lift_r" type="float" title="Lift Red" description="Amount of red in shadows">

Now i'm trying to get a color wheel as widget in MLT, but the color wheel function as widget is not installed in MLT by default. How can i get the color wheel to appear as widget in Openshot and make this color grading effect functional?
