One feature I like from Visual Studio is when you have a sytax style error that the editor picks up (the infamous red squiggly line), it placed it with the line number and problem in a listview in a task window (similar to the Log/Transfers/etc windows along the bottom.) That way, if you don't notice an error right away, you can always look at the window and see if any exist, and quickly jump to it. I find it annoying when trying to clean up text with PolyStyle and nothing changes because of an error like a non-matching */ or something I have to try and hunt down.
