bug in Graphwalker Studio - Cannot load more than one json at a time. #290
Description
When a json has been loaded into Studio, opening a new json file will ALWAYS take the place of the last loaded file, no matter what. This will also rewrite any changes made to the previous graph. This prevents any models that use shared states, as it is impossible to load more than one.
Expected behavior - Importing a new file opens it in a new tab, and adds any shared states to the current instance.
