Hi,
I love KDEnlive. I used it for few years but due to lack of custom plugin development possibility, I moved to DaVinci Resolve.

Please, to make KDEnLive great, we need to have a feature that allow us to develop custom plugin to create custom transition, custom title VFX and so on.
So an easy way to develop and import custom plugin in order to improve video we create with KDEnlive.
