In the Project Explorer you can not only see the ModuleTree of the current project but you can also access a lot of important windows. One of these windows is the Pad list and its appropriate subwindows - the Attributes window and the Connections window.

The Pad list shows all the Pads for a module. Pads are connection points of a module or node. The button line of the Pad list shows the name of the selected module. The selected Pad is highlighted. You can set the type and orientation of the Pads as before (with the shortcuts 'r' (orientation right), 'b' (orientation bottom), 'l' (orientation left), 't' (orientation top) and 'h' (hide) or with the context menu of the Pads in the Pad list).
Use the 'Freeze' button if you want to select a second node/module or surface element without wanting one of the Pad lists to update.

To be able to connect the Pads of multiple folded nodes easily you could export these Pads with the 'Export' button in the Pad list or with the context menus by clicking on the Pads in 'Circuit View' or in the Pad list.

As some modules have a lot of Pads we distinguish between Pads and Variables now. Pads are connection points of a module - this means they are variables that can be connected to other Pads. Whereas Variables cannot be connected to other Pads or Variables. You can dongle to the Variable list of the selected node by activating the 'Vars' switch on top of the Pad list window.

Connections can be made with the 'Store' and 'Connect' buttons. You can also access this functionality from the context menu (right click a node or surface element).
There is one Connections window and one Attributes window for both Pad lists. They show the information from the selected Pad of the selected list. The Connections window has two pages for displaying information - the 'Routings' page and the 'Synapse' page. The 'Routings' page shows the hierarchical routing from one Pad to the others (which could indeed pass through multiple Pads).
The 'Synapse' page just lists all the Pads that are conntected without considering any hierarchies. This means also the Pad of the selected node is listed on the 'Synapse' page. This way it provides an quick and easy overview of all the points that are affected by a change in the connection network.
