It seems that Donate Plus isn't set up to handle fractions (i.e. decimal places) in donations. It only registers/displays the amount rounded down to the nearest dollar, meaning that if a user does submit a donation, say of $1.50, only $1 will be added to the total and displayed on the recognition wall, which is far from ideal.
I wonder if anyone has adapted this plugin to work with fractions/decimal places, or knows how this could be done?
Related to this is how to use the amount of the donation after PayPal has subtracted its fee, rather than the full donation amount. This would be a more accurate total. Ideally the full amount would be used on the recognition wall so that the user gets to see the full amount of their donation on the wall, but the actual amount received would be used for the total.
