I've always noticed that when you have waveforms displayed in the timeline, it's very very hard to see a locator on an audio track. I know you can change colors but I wonder if there could be a way to make locators able to be different shapes or sizes. That way if your doing very audio intensive work you could set up the locators to stick out amongst the waveforms. It could be a help in 101 other ways too. I also once asked about making them able to mark a range of area, I guess this would be similar to FCP, but it ain't a bad idea.
