Additional Software gets opened multiple times

See screenshot in attachment.

For example:

• If you click multiple times on the gear button in the persistent storage configuration.
• If you open it multiple times from the Applications menu.

It’s especially annoying when doing:

• Start without a persistent storage.
• Open Additional Software.
• Click on the link to “create a persistent storage”.
• Create the persistent storage.
• Click on the gear button in the persistent storage configuration.
• → The same window opens again…

I don’t think it’s a big deal but if that can be solved it will look much more polished to people who might otherwise face this.
