In the PL/SQL syntax color it would be nice to include options for each style of comments
The styles are: -- SINGLE LINE ; /* */ MULTI-LINE ; /*+ */ HINT and --+ HINT
So with different colors for SINGLE LINE, MULTI_LINE and HINT it is easy to understand intent of comment. I use SINGLE LINE that starts in column 1 and a way of removing code. If I could color differently I'd set it to a faint color, so to hide. And HINTS could stand out.
