I'd like to suggest the idea for bulk delete of downloaded packages, in package manager
I don't see a way to delete multiple, UNinstalled, downloaded packages
Only 1 at a time.
If I by pass package manager,
go into site hosting account and bulk delete the package zip files,
is that going to be problem for the package manager listings?
If they are uninstalled it's not a problem, the page is created unzipping on-the-fly the packages and grabbing the info from them, so no problem.
Maybe also along the same lines an option/link to delete the package when uninstall is complete. Helpful when I am doing addon testing.
