-----------    Update log    -----------
----------------------------------------
-- Update (20 Mar, 2019)
-- Improved freestanding for "No fake" anti-aim mode

-- Update (19 Mar, 2019)
-- Freestanding is now a separate option and works with all anti-aim modes (still requires Vector3.lua)
-- Now using one key to switch sides instead of two (put hotkey style to "Toggle" to make manual anti-aim work properly)
-- Implemented "Static body yaw" to work with "Static" and "Jitter" anti-aim modes (all credits go to abbie)
-- Code improvements

-- Update (16 Mar, 2019)
-- Removed "Experimental" anti-aim style
-- Added "No fake" anti-aim style
-- Added "Freestanding" anti-aim style, based on "Static" anti-aim style (requires Vector3.lua - all credits go to Horse)

-- Update (13 Mar, 2019)
-- Changed behavior of "Experimental" anti-aim style (now works similar to Jitter)
-- Changed combobox to multiselect for indicators (they now show your fake for both anti-aim styles)

-- Recode (04 Mar, 2019)
-- Added "Experimental" anti-aim style (most useful with scout)
-- Removed two features: "On shot anti-aim fix", "Reposition indicators"
-- Now using two different hotkeys to change sides of the anti-aim (if you want to use one key for both sides, set the first hotkey type to "On hotkey" and the second one to "Toggle")
-- Indicators for "Static" anti-aim style show your fake angle; indicators for "Experimental" anti-aim style show your real angle

-- Update (01 Mar, 2019)
-- No longer using edge yaw in anti-aim list
-- You are able to use "fake duck" by default, but enabling "on shot anti-aim" and "on shot fix" will cause automatic deactivation of this feature
