Object Editor Per Project?

Hello! Newcomer here.

Is there any way to have a different collection of predefined objects per project*? Because as far as I’m aware the Objects Type Editor is constant and is globally used across all projects. Is there an option/way to make it use a file from the current directory of the edited map? Something like how Automapping is differentiable per project?

This would be a suggestion if not already implemented.

You can create multiple object types files and switch between them, but for now the switching would need to happen manually. You can do this via File > Choose Object Types File in the Object Types Editor.

Tying this to a project is definitely planned. See the following issue on GitHub:
