The switch to "To Workspace" was done to accomadate users who want to be able to have the Probes used in a library block (this is not possible with Scopes). As for the naming limitation, until I can figure out a better way, it is up to the user to provide unique names (I tried using genvarname, but there is a 64 char limit). The names are updated during model update. As for simlog, currently the only options are All or None. Once additional functionality is added here, I will be able to add a logging option.
Thanks for your feedback.
