As a Roblox developer, it is currently difficult to edit datastores in Roblox studio. Even with the upcoming datastore 1.1 change I do not believe it will allow you to edit data stores more easily . The provided solution is to use a paid plugin, that is data store editor , but I feel it should be a builtin feature in studio for everyone.
If Roblox is able to address this issue, it would improve my development experience because it would be more user-friendly and more productive instead of going in game , printing a list of the data stores with keys and using setasync or updateasync to update the data stores. If combined with 1.1 it will also make it easier to restore data.
Roblox could even team up with the person/people behind the data store editor plugin and make it better than it already is.
