In the pl/sql editor window when you fold code just the key word remains in pale grey. I think this would be more useful if the whole first line was retained so that it is easier to identify what code has been folded.
For example instead of:
You would see:
CURSOR c_get_acc_dets IS...
Still in pale grey so it's still obvious that it has been folded.
Also although select, delete and inserts statements can be folded update statements can't. Please can this be included.
