Recently, I decided to take matters into my own hands and the add right-click functionality I need to Timeline. I appreciate how you guys made the code open source. So I add the editor and runtime Timeline scripts to my project... but am unable to create a two-way dependency between my code and Timeline's. For that, I must delete the Assembly Definition files inside Timeline (because circular dependencies are not allowed). But if I delete the Assembly Definition files, I get four protection errors with internal Unity classes. This is with Unity 2019.2.0b5 and Timeline 1.1.0. Is there a way around this?
