Highlight unvisited or uncaptured portals.
| Fill color of portal | Description |
|---|---|
| Purple | The portal is unvisited, also uncaptured. |
| Red | The portal has been visited, but uncaptured. |
| Transparent | The portal has been captured, also visited. |
| Blue or Green | Zoom level of map is too small to judge visited or captured. |
If the cache option is enabled, portal history will be cached in your browser or app. The option is enabled by default.
Any portals are sometimes shown as unvisited even though it is visited. Reloading iitc often fixes this problem.
