In big boards you have to scroll over large areas in order to reach the the desired objects.
Quite often a discussion or workshop follows the connector lines of different objects (frames, boards, etc). Since they can be quite far apart from each other it would be very handy to jump quickly to the next object by clicking on the connector line.
We use connection lines to link up related items and user feedback on a big board, would be very useful to be able to ‘follow line’ or ‘highlight connections’ for the purposes of navigation and presentation.
