There's an awful lot of clicking involved when you use the dialogues for selecting signals, track, OHLE, scenery, and stock. Could the dialogues be modified to remember the last five (or whatever) items used in the layout, which could be selected without navigating through the tree? Or maybe allow user-defined favourites for the layout to be selected directly via programmable buttons in the link dialogue, etc.? (Even longer term: allow assemblies of track and scenery to be saved as macro objects that can be stuck directly onto the current node - would be great for relatively complex things that occur many times in a layout, like tram stops, double slips, flyover junctions...)
