it was a regression which appeared in version 7.2

the add to catalog was checked by default

Do I understand it right:
Before 7.2 it was not checked by default but in some earlier versions.
In 7.2 it was checked by default.
In 7.3 it is not checked by default.

I have a 7.2 version where it is not checked by default. I have downloaded SweetHome3D-7.2-linux-x64.tgz on 2024-01-02. The top level folder in the archive is from 2023-09-22T14:32 as (not completely checked) any other file in the archive.
