Backstory: Since the update to Atom 1.6 i experienced crashes. I found out that some package is taking away the memory (memory leak), so after disabling and enabling packages, i found out that the package git-tab-status caused the issue.
However, looking at the github repository, it says that it is deprecated. Also, the package has been removed from the package thing on this site.
So i would suggest a “feature”, that notifies about packages, that has been deprecated/deleted. Maybe you could reuse the “Deprecated Packages” in the settings. This would help finding such packages and removing them if they cause issues.
