I found it is quite interesting that I would like to bring up this question if someone do care about this.
I have a big class to me that it is easier for working if using the class selection panel on top.
But unfortunately if the function contains something like CCARRAY_FOREACH, the class cannot be shown in the list.
And when you are inside the loop, only the CCARRAY_FOREACH loops will be shown.
Just wonder if someone care about this and trying to fix this.
