Roblox plans on releasing it's asset manager to replace the already perfect Game Explorer and Properties that we're already used to. Let's stop roblox from making it harder on developers to access in game parts and assets.

ACCORDING TO ROBLOX: 

"Why is Asset Manager replacing Game Explorer?
Currently, asset management is scattered across different places e.g. Create, Account Inventory pages on the website, Inventory in Toolbox / Game Explorer in Studio. Our long-term vision is to have a single place for managing all assets: Asset Manager."
