#Misc addon dev Notes:
# when editing an addon you can more quickly have it updated by Blender using the following
# you can symlink the installed Blender directory to target your editing directory.
# Then whenever you save the __init__.py file, Blender will know it needs to be reloaded 
#   when you untick/retick to activate addon (in the Blender Preferences/Addons/section). See:
#https://www.matthewsessions.com/blog/developing-blender-addon-tips/
#in windows from an admin level command prompt (not a powershell)
#mklink /J "C:\Users\dgm55\AppData\Roaming\Blender Foundation\Blender\2.92\scripts\addons\3d-print-toolbox-test" "C:\Users\dgm55\source\repos\StressTestAndSupportsVisualisation\3d-print-toolbox-test"
# BUT don't forget to keep incremental backups...

# Notes on class naming conventions (since Blender 2.8)
# see: https://wiki.blender.org/wiki/Reference/Release_Notes/2.80/Python_API/Addons for the naming convention

#Classes that contain properties from bpy.props use Python's type annotations and should be assigned with a colon, not an =
#class MyOperator(Operator):
#    value: IntProperty()

# Add-on's should assign their classes to a tuple or list and register/unregister them directly (see functions below).
#Module names are the name of the file (as per normal Python)
#Class names within each module *MUST* be: UPPER_CASE_{SEPARATOR}_mixed_case
#where separator is one of:-
#Header -> _HT_
#Menu -> _MT_
#Operator -> _OT_
#Panel -> _PT_
#UIList -> _UL_
