Just a quick suggestion which might have been brought up previously. I was wondering if it might be possible to implement a “snapping” capability for the digitise and pole manipulation tools. While I would usually use a GIS application for digitisation, it can be useful to quickly sketch things up in GPlates, and these sketches would be much neater if I had the option to snap the vertices I draw to other nearby vertices. Similarly, when manipulating reconstructions of individual point features (e.g. vertices of a deforming network) it would be useful to be able to snap points onto others. Perhaps there is already a workaround for this which I am missing?
