 What do you think if we use two underscore (__) to join the basename with
 the rest?

 basename__01, basename__02, etc.

 {{{
 #!python
 >>> import re
 >>> m = re.match("^(?P<name>[a-zA-Z0-9]+)__(?P<id>\w+)$", "horizon__000")
 >>> m.groups()
 ('horizon', '000')
 >>> m.groupdict()
 {'id': '000', 'name': 'pippo'}
 >>> m = re.match("^(?P<name>[a-zA-Z0-9]+)__(?P<id>\w+)$", "tile__000_001")
 >>> m.groups()
 ('tile', '000_001')
 >>> m.groupdict()
 {'name': 'tile', 'id': '000_001'}
 }}}

 So maybe in the future the GUI would be able to group maps following the
 rule "basename__*" and visualize them in the wxGUI Animation or something
 else...
