You can hide connections that you are not longer actively working with, or added to GetBusy by mistake.
Browse to the connection in your connections list and choose Hide from the "..." menu next to their name.
All hidden connections are collected together and can be accessed via the "..." option at the bottom of your connections list.
You can unhide connections by opening them from the hidden view and choosing Unhide from the "..." menu next to their name.
Hiding a connection does not delete your previous activity with them and you'll still be notified of any new activity.
