Indeed a better sdk will be better.
I actually also hope that sdk can recognize which parameters of the object are activated in the object manager.
I know that because c4d supports opening multiple object managers at the same time, this is really convenient.
But it will also make it impossible to know which object manager the user is using, so there is no way to identify it in the current SDK.

@blastframe Hello, Anitools actually supports switching Timeline, but the user needs to manually select which Timeline to use.

At the earliest I used a command menu to switch. .

In the v1.05 version of Anitools, I added a panel to switch the Timeline window.

The method used in my FreeEase plugin is also good. If the UI of the plug-in is not too complicated, using ComboBox to switch is a good solution.
