Hey everyone, I don't know about you guys, but the default icon set for mintUpdate doesn't really make sense to me. I mean, what do padlocks have to do with updates, right?
So after some time of working with Gimp, I came up with alternative icons based on Mint logo.
Grab it here: http://gneek.narod.ru/mintUpdateIconset.tar
After downloading the package, untar it somewhere and change mintUpdate's preferences (Icons tab).
