I have docked ligands into a protein and saved them in pdb format, but there is no clear way to open them. **Developer response:** Thank you for your feedback. You are absolutely right — earlier versions of the app only supported downloading PDB structures directly from the RCSB. We’re happy to let you know that this functionality has now been added. The latest version of the app allows users to import their own PDB files, including structures with docked ligands (ATOM / HETATM records) stored locally on the device. You can import your custom PDB files via the file import option in the app and view both protein and ligand structures together. We sincerely appreciate your feedback, as it directly helped prioritize this improvement. If you encounter any issues or have further suggestions, please feel free to reach out at any time. If this update resolves your issue, we would greatly appreciate it if you could consider updating your review. ## Frequently asked questions about ProteinViewerApp ### What is ProteinViewerApp?
