# Updated
# - Panel layout > updated to match 2.8 styling
# - Added cleaner eye toggles for past and future
# - Icons to some buttons

# Added
# - Option to work with linked rigs > needs work InBetween as we need to target Parent rig
# - In Front option > show mesh in front of onion skinning
# - Shortcuts > for easier and faster workflow
# - Addon preferences so shortcuts can be customized
# - Panel feedback when nothings is selected or wrong object

# Fixed
# - Possibly old onion skinning when another file is openened
# - Linked rigs and local object/mesh also show onion skinning

# Ideas
# - Auto update when working on posing > could be handy? > need fedback from real animators
# - Added option to do multiple objects > this would need merge of objects, not sure will still work properly
