Multiple cursors only seem to work for simple things, which is good enough a lot of the time. However, incremental search in a macro is very useful, for example.
Maybe it'll become enough of a database that it'll be much easier to figure out how to add the "missing" features in Emacs. Currently 720 questions. Let's see how often it's used.
What you would do with an incremental search inside a macro, I'm much more inclined to do with a regex search and replace. I generally only use search at the end of my macros, to find the next "instance" that need to be run over.
