AI Summary: The `readopentopo` function in TopoToolbox3 requires an API key from opentopography. Previously, users could store this key in a file within the `IOtools` folder, but this method is no longer viable for TT3 installations from mltbx files due to inaccessible directories. The issue seeks a new, more user-friendly and robust method for managing these locally stored API keys.

Complexity: 3/5
