Variable Giftbag._transferStandard(address,address,uint256).rTransferAmount (#481) is too similar to Giftbag._getValues(uint256).tTransferAmount (#519)
Prevent variables from having similar names.

Additional information: link

Giftbag.slitherConstructorConstantVariables() (#176-622) uses literals with too many digits:
- _tTotal = 1000000000000000 * 10 ** 9 (#189)
Use: Ether suffix, Time suffix, or The scientific notation

Additional information: link

Giftbag.cooldown (#210) is never used in Giftbag (#176-622)
Remove unused state variables.

Additional information: link

Ownable._previousOwner (#61) should be constant
Add the constant attributes to state variables that never change.

allowPreTrading(address,bool) should be declared external:
- Giftbag.allowPreTrading(address,bool) (#617-620)
Use the external attribute for functions never called from the contract.

Giftbag._approve(address,address,uint256).owner (#344) shadows:
- Ownable.owner() (#73-75) (function)
Rename the local variables that shadow another component.

Giftbag._previoustaxFee (#206) is set pre-construction with a non-constant function or state variable:
- _taxFee
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
