Maybe I’ve just missed something but is there a command to close any/all open paths in a glyph? FontLab calls it ‘close open contours’ and it’s a faster way than finding endpoints, selecting them, choosing pen tool, drawing a line and then exiting drawing mode. Ideally it’d have a nice shortcut too 
@mekkablue has a “Close Open Paths” script in his repository:
fyi.
Lovely, thanks! 
you can select two nodes and select “Connect Nodes” from the context menu.
