The Links Panel in InDesign is very useful for checking the color, dpi, and status of a particular link. But there can be a lot of information, actually there can be even more than what it defaults to.
If you go to the Links Panel and select the panel menu by clicking in the upper right corner of the dialog box, you can select Panel Options. Here you can change the information that is displayed. This might make is easier to see what is important to you at a glance.
