Sorry, I didn’t mean to imply that this version would control it. Your question just reminded me of this option: Options -> Schema Browser -> Right Hand SIde -> Show Body when Package Name Selected.
What version of the beta do you have? In the current beta, if you click on a “Package Body” in the Schema Browser History (or navigate button), it will go to the package body. If you click on a “Package”, then it will go to the spec.
If you are a few betas out of date, try pulling a new one. I removed this option for a little while shortly after adding it because I thought it might have been causing a bug. Turns out it was not the cause of the bug, and only a few betas ago did I add this back in.
