We have a managed released package currently undergoing security review. While that is happening, we would like to make some changes to the tab layout of our application. Unfortunately, it seems that I can change very little to do with our tabs in our managed released package. I would like to get the package into the hands of beta testers, but I need to make the aforementioned tab changes first. Is there any way at all that I can do this? I would rather not have the beta testers install an unmanaged package, as there are post-installation steps that they would have to execute manually.
What are our options here?
