 - It is possible to export the inputs to a **CSV** file for convenience. This will result in two relevant heading names as seen in the table followed by the rows of inputs.
 - Likewise, it is also possible to import inputs for both panorama IDs and URLs from a CSV file. The first column is expected to be panorama IDs or URLs, and the second is expected to be the file save paths. Only the first two columns are considered, and all inputs must be valid. The first row is ignored to account for **headings**, otherwise is included if valid, and the rest of the rows must be valid or else the import will fail. The import will overwrite any existing rows in the input table upon confirmaton.

 ## Panorama Rendering
 Another feature of the app is built-in rendering, allowing panoramas to be rendered onto a square projection with the ability to control the camera view. Upon entering the panorama rendering section, this is shown:

 - There are two methods of inputting the panorama, either by providing the **panorama ID** directly or providing a valid **Street View URL** and allowing the program to extract the panorama ID from it. Select the one you are more comfortable using.
 - The panorama zoom must be set to either 4 or 5. In summary, zoom 4 rendering is faster and less memory intensive than zoom 5, but zoom 5 has the better quality than zoom 4. Ensure you make the appropriate choice based on your requirements.

 Upon starting, firstly, the panorama tiles must be downloaded, and then the cubemap for rendering purposes must be generated, taking a few seconds. Once done, the projection screen is then available:

 - You can set the square length (width/height) of the projected image between 64 and 625 pixels.
 - For advanced users, there is the option to manually adjust the yaw, pitch and FOV angles too, simply by modifying the corresponding inputs. All angles are in degrees.
