As a Roblox developer, it is currently too hard to import an entire directory in Studio. Currently you have to get the user to select every file in a directory for it to be usable.
My suggestion here is to add a Directory class with PromptImportFolder
If Roblox is able to address this issue, it would improve my development experience because I could then write plugins that can take advantage of directories instead of having to ask the user to select all in that directory.
