Connection Labels
Types and Labels
The connection lines between cards all have a connection type. These connection types have a name and color that can be shared amongst the connections on your space.
By default new connections will use the last connection type, but you can make new connections use unique types/colors by unchecking Use Last Type
Use connections and labels to add flexible meaning, grouping, and structure to your spaces.
Bulk Edit
Paint to select multiple connections lets you assign them all to the same connection type.
