This would be a killer feature!
Currently I use Eclipse/Aptana along with ST2 when I need to do global search and replace. That may sound silly and I'd love to completely get rid of the former and do everything in ST2 but Global Replace is just a too dangerous operation to perform it blindly, without any preview and selective replaces. Having ST2 open all edited files in unsaved state is helpful but not as transparent and efficient as what is being suggested here, I hope you agree.
Now ST2 doesn't need an interface as bulky as in Eclipse, the current search results window would be perfect, if only we could edit it and have the edits applied to appropriate locations in files!
Please consider implementing this!
P.S. This has also been suggested by Martin Stabenfeldt in this comment.
