When adding conditions to the "Find items that meet the following criteria" and "Then" sections of Evolutions "Edit Rule" dialog the new conditions should be created at the top of the conditon list instead of at the end of the list so that a user doesn't have to scroll down every time they want to add a condition. Bug 239817 also mentions this issue but is marked for an old version of evolution and its solution is a bit too complicated for something like this.
