I have read the ‘Navigraph’ page. If one has to comply with the guideline, prior preparation of chart content before streaming is needed . This is additional work which many would like to avoid. Therefore, can you add a floating label containing the string “Copyright © 2021 Navigraph/ Jeppesen” which remains present at various zoom level and as a chart is panned? Having this simple feature will ensure compliance with the brand guideline. I would prefer that this feature can also be turned off when not needed (e.g. personal use/no streaming or publishing).
