As a Roblox developer, it is currently too hard to persist Studio-only objects such as template items for a plugin, or debugging tools that would only be usable in Studio.
The issue lies in the lack of a reliable storage service that persists in the place that isn’t also usable by a live game (only loaded in Studio).
StudioService can be used to store objects from plugins but it does not persist between sessions since StudioService doesn’t save its child members.
If Roblox is able to address this issue, it would improve my development experience because I could save studio-only objects in a place file and keep it around for future usage.
