@maxcapodi78 I defined active_design at desktop.py level because it is also used at this level, if you think it does not make sense, we can discuss.

@Samuelopez-ansys Just wondering if there is a way to avoid the latency that such changes will add.
For example, the property oeditor now contains

                if is_linux and settings.aedt_version == "2024.1":
                    time.sleep(1)
                    self._odesktop.CloseAllWindows()

I've briefly looked into our code base and it seems that a lot of classes tend to access this oeditor property. Could we have some cache mechanism to know that all windows are already closed and avoid this time.sleep(1) call ?

@SMoraisAnsys I did not find a method in the AEDT API to get this information... it is impacting only Linux in 2024.R1. Ansys development team is checking how to fix this in issue in 2024R2. So we need to decide if we want Circuit in 2024R1 in Linux, or not :)

LGTM, I proposed a few changes though
