I often use TortoiseSVN for merges instead of IDEA because of the performance problems I've seen when selecting which revisions to merge (see IDEA-16312). In doing so, I've found a feature that I really like and would like to see integrated into IDEA as well. Assuming that you do not already know which revisions you want to merge from on the Integrate Project dialog, clicking on the Specified "..." brings up a svn log window from which you can select a single revision. It would be a nice shortcut if that dialog allowed you to select a range of revisions instead of just one. When multi-selecting, the "Integrate Project" dialog would have both Source 1 and Source 2 completely populated. This is usually the type of workflow our engineers go through when merging. How often do you really merge between two different source URLs? I haven't ever, and I can't really imagine how it would be useful in any but the most edge-case scenarios. I've included a screenshot of TortoiseSVN revision selection screen (with multiple revisions selected).
