Love the plugin...I had a specific need for the plugin that I wasn't sure could be addressed quickly, where through some fundraising we were doing, the company we were partnering with does matching donations. I added the matching donations piece to both the plugin page and the admin side so you could turn it on or off. I noticed you've done an update for designated funds, so I thought I could just send you the code if you'd like to merge it into what you have before you make the changes to obfuscate the email as well. Had to dig into it a little bit as some things were hard coded, but it's worked out nicely with reports as well. I'd like to add the new features you are putting out but didn't want to overwrite the changes that have been made of course, and thought it would be a nice feature for others to have.
You can see the addition at my FreedomRunUSA site.
