Question about implementing a custom UI in an After Effects plugin

Hi, I’m developing a plugin for After Effects and I’d like to use a custom user interface instead of Adobe’s default one.

How can I integrate a custom UI into my plugin?

What kind of extension are you talking about:
C++ plugin API, ExtendScript, or CEP panel?
I assume you talk about an ExtendScript, since this is limited to a fixed set of UI elements. In that case the answer is to develop a CEP panel instead of a ExtendScript script.
If you really mean a (C++) plugin and no script, then you can use Qt, for example, to create a custom UI.
