I noticed an issue with the Auto Withdrawal:
The text input field for specifying the amount (threshold) for auto-withdrawal has HTML attribute maxlength="3" so if you want a value less than 1.0 your only options are tenths of a coin: 0.1 for example.
I wanted 0.201.
I was able to remove the maxlength attribute within my browser and submit the amount. It seems to have worked, meaning there is no maxlength=3 validation on the code which processes the HTML form.
Please remove this attribute.
