Hi Andrei, sorry no there isn't any way currently to enable history for booleans.

That's because when you do a boolean, the object is replaced by the edited result, the original object is not stored in the file anymore.

For the current history system to work, the input objects that went into the command that generated the object need to be available in the current model.

In the future I want to store previous versions of objects in some companion history data file so they could be found and used for things like this. That will involve a lot of work and so I'm not sure when it will happen.
