v0.0.7

TurtleThread now uses the TNavigator class from the builtin turtle.py module to handle navigation (but copying the source code instead of importing to ensure compatibility with systems without TKinter).

Note: Before this release, TurtleThread used the same coordinate system as TurtleStitch, which has a flipped y-axis compared to turtle.py. You may therefore observe that your patterns are flipped compared to the previous version.
