I am glad you find it useful.

In the picture I cannot really see it, it's just not good quality
screenshot or the cursor disappears?

I will try to add the settings of the cursor width and color when I have
more time, the only problem is to create the gui for this. In the meantime,
if you really need to change it, you can always edit the line which draws
the cursor:

Index: gui/wxpython/mapswipe/mapwindow.py

     def DrawMouseCross(self, coords):
         """!Draw moving cross."""
         self.pdcTmp.ClearId(self.lineid)
-        self.lineid = self.DrawCross(pdc = self.pdcTmp, coords = coords,
size = 10, pen = wx.BLACK_PEN)
+        self.lineid = self.DrawCross(pdc = self.pdcTmp, coords = coords,
size = 10, pen = wx.Pen(wx.Colour(250, 250, 250), 3))

So tuple (250, 250, 250) is the color as R, G, B and the 3 is the desired
width (currently it uses width 1).

You can then compile it with 'make' in the gui/wxpython directory.

Best,
Anna
