[josm-dev] UI development

[Gervase Markham]

I'm trying to update my proposal for the JOSM UI based on the feedback. 
However, I'm having trouble understanding some of the things people have 
written.

http://wiki.openstreetmap.org/index.php/JOSM/UI

- Someone has added various actions related to GPX track points to the 
"possible actions list". However, as I understand it, GPX track points 
are just points in a particular layer - i.e. they would be manipulated 
in all ways the same as nodes, when that layer is the current layer. Is 
this true? If not, what have I missed?

- Someone has added "Delete segment". I thought segments were no longer 
part of the data model?

- Someone has added "Split ways with duplicating nodes at identical 
positions (yielding not connected ways)". I'm not quite sure what that 
means, but I thought that was how splitting a way would work. What other 
options are there?

It has been suggested that the same mouse button could be used for 
selection and panning; the map is panned if you click and drag on an 
area with no nodes or ways. However, it seems to me that this would have 
problems when you are zoomed out, because there would be no area of the 
map to grab hold of, because there are nodes everywhere. What do people 
think?
