Would be good to see syntax added in scripts you can flag standard packages that need to be included. So when installing a new unity package it will be able to let you know dependencies are required and allow you to pull them in as well. Currently, if a asset store package requires something like 'post processing stack' it will either include it in the package or include it in the install instructions. Neither is optimal. I also see this with 'standard assets' which I hope will also be included in the package manager in the future. Also, some meta data to test the version of included package would also be great, so older packages can be supported better in other packages. Looking forward to the extended support for all .unitypackage files will make management of internal frameworks a lot easier too.
