    I agree with all these suggestions and we should register them in JIRA.
    I can't guarantee that I will immediately add every checkbox that is
    requested, but these issues will still be helpful. When we have a
    critical mass of them coming from many users, we'll "refactor" them to
    form a consistent direction for the future Modeler.

    In fact I am already looking into support for "cut-and-paste" and for
    the navigation history in the modeler (I am thinking of "back" and
    "forward" buttons, just like the web browser). These should supersede
    (2) and (3), but specific usage patterns are still helpful.

    Same goes for the comments posted on "Modeler Question" thread by Kevin
    and Michael (Kevin already opened CAY-208, thanks!) - adding support
    for multiple objects selection in such operations as "sync", "delete",
    etc. is in the plans so having the specifics mentioned in JIRA should
    help to direct and expedite the implementation.
