It is very convenient that you can set yourself to automatically spend VP for power. However, the following should be implemented:
If you have passed, and your power income will max out your VP, you should automatically decline spending VP for power.
For example, I have it set to automatically spend 2 VP for 3 power. I have 1 power in bowl 1 and 4 power in bowl 2. I have 8 power movement income. My power movement is going to be maxed out when I receive my income when the round ends, so I should decline spending VP for power until my turn starts, as there is no situation where that would be beneficial for me.
It's very annoying to have passed and come back to the game to find I have spent a bunch of VP for power when I already would have been maxed when I got my income.
