Bug: Unable to rename an empty Pinboard

[CHENGJOY]

Hi there,

Thank you for this amazing app! I found a minor bug regarding the Pinboard renaming feature. When a Pinboard has no items pinned to it yet (showing "Nothing copied yet"), I am unable to successfully rename it.

Steps to Reproduce:

1. Open the app and create a new Pinboard (e.g., "New Pinboard").
2. Ensure the Pinboard is completely empty.
3. Trigger the "Rename Pinboard" dialog.
4. Type in a new name and click the "OK" button.

Expected Behavior:
The Pinboard tab should update to the newly entered name, even if it is empty.

Actual Behavior:
The rename action does not take effect, and the Pinboard retains its original name.

Environment:

• macOS version: [15.7.7 (24G720)]
• App version: [ 1.2.0 (8) (8)]

I have attached a screenshot of the rename dialog for your reference. Let me know if you need any more details!
