After Effects effects previewer UI
A UI of your effects that allows you to layer effects in a previewer to see the results before applying. This would be especially effective if you have a lot of effects and not sure what they all do.

Hi Jessica
I don’t use Lightroom, but it would be something like trapcode’s particular. Pop up your effects panel with all of your effects on one side, your layer on the right. The start applying effects to get the look you want. Then save and the effects are applied. Does that make sense? -

Hello Sharon,
Is the request to have a previewer similar to how, say in Lightroom, you see a color style on an example image before you then use it on your own image? (i.e. https://helpx.adobe.com/lightroom-cc/using/edit-photos.html#profile) I imagine in AEs case there would be an example mini video clip that showed the effect in use.
If that is not how you imagine it - could you explain your idea further?
All the best,
Jessica
