As a Roblox developer, it is currently impossible to work efficiently with tool instances as they are treated as Folders rather than models, making it difficult to move them around the game world.
Example: I am trying to create a tool rack in-game for weapons, however trying to do this is difficult without grouping the models (which adds complexity to the mechanic) is generally really tricky to achieve.
If Roblox were able to address my issue, it would allow for better use of the Tool feature within games by developers and better creation of tools within studio.
