Hi, if i remember well, Forest Tools was implemented before there was a "Display->Disable Object" option (which is linked with the checkbox in the Lister).
Instead, we used the Geometry List, setting all entries to "Disabled". It has the same effect, although is less elegant.
I will check it we can change that, to work in the same way than RailClone.
I also added your suggestions to our wishlist, regarding the freezing / box options.
Thanks for your feedback,
