'Split View' in OpenSpace allows you to view two captures side-by-side. To get started, click the 'Split View' button.
This will open the Split View. From here, you can navigate between different Capture dates by clicking on the date button.
This will then bring up a calendar allowing you to select a date that has a Capture.
NOTE: You can use Split View on Captures that are on different sheets.
Once selected, you can click the 'Lock' in the middle of the screen - which will automatically lock both images and allow you to navigate them simultaneously.
Once you've finished viewing, you can close the Split View by hitting the X.
