I also did a change with movement and attacks. I allowed that as a Standard Action, you can make a number of melee attacks equal to half your current maximum of attacks rounded up. In addition, you can spend a swift action to gain one additional attack, but this additional attack must be one of your attacks that's 'left over.'
For example, if you have four attacks (+20/+15/+10/+5), you use a standard action to gain two attacks, (+20/+15) and as a swift action you gain one more attack (must be the remaining +10 or +5 if you prefer).
