Please bring back better icons!

Hi. Thanks for writing SourceTree; overall it's a great git client. Unfortunately, the new Toolbar icons in SourceTree v2.2 are very small and have removed all use of color, so they are much more difficult to see/read/use than those in previous versions. Please make better icons (larger ones with use of color) available for the toolbar. In the meantime, I will be sticking with v2.0.5.2 until better icons are made available. Thanks.
