It's getting better day by day, new features:

• You can now generate a UV Mapping image with all polygons uv data
• You can now copy and paste UV data from poly to poly(right click a poly in right side menu) [1]

• You can swap / mirror / flip UV data

• In poly-editing mode with drag editing settings, when you are dragging a vertice, you can use the arrow keys for a finer control (it's based on XYZ decimal rounding)
• There are more vertices for editing a side of poly (2 for triangle, 4 for a quad)

Changes:

• Renaming a poly will now require to open a menu by right clicking the poly in the right side menu (see [1] photo).
• There is now a setting to show all poly in uv editing mode.  (true by default)
• There is now a setting for image size for generating a uv mapping file.  ( 512x512px by default, sizes from 16x16 to 4096x4096)
• XYZ decimal rounding is set to 0.01 by default (old was 0.1)  (old preferences file is obsolete)
