There are several icons that appear on claims to indicate their status and help you quickly navigate through a discussion.
A blue dot indicates that you have not interacted with the claim since it was created.
If a claim is “stacked” (i.e. you can see another card underneath the claim), it means there are children claims located underneath it. If the card underneath the claim has a blue highlight on the bottom of it, it means that there are unseen changes, claims or comments located underneath.
A speech bubble icon opens the comments section of the claim. If it is blue, then there are new comments that you have not yet seen.
A blue pencil indicates that there have been edits to a claim since the last time you clicked on it. If a claim has been edited multiple times, this will become a dot-pointed list icon.
Blue interlocking squares indicate that a claim has been linked to this location. A downwards arrow icon indicates that a claim has been moved to this location.
When claims are entirely grey, with a trash icon, they have been deleted. If they are grey with an upwards arrow icon, they have been moved away to another location. An upwards arrow from trash icon indicates that it is a previously deleted claim which has been restored.
When claims are highlighted yellow, an Editor or Admin has marked them to indicate that there is an issue that needs review (see Types of Mark).
