Usually when I'm in the plugin and I select Copy->Replace in the cbom view, I intend to replace just the item in the active assembly with a cloned item (the alternative workflow would be to clone and then use Solidworks' Replace Component feature). I almost never want the plugin to simultaneously modify any assemblies I happen to have open in the background like it currently does. If the plugin is going to modify BOMs other than the immediately obvious and active BOM, the user should be made explicitly aware this is happening so they don't forget they have a few other assemblies open and accidentally replace a component in 10 locations when they meant to do one.
Suggested resolution: Prompt the user to choose whether they mean Replace just in the active assembly/BOM (default) or if they happen to really mean Replace in all assemblies they have open at that time - there should probably also be some indication of how many assemblies are going to be affected by this action so the user can make an informed decision.
