To add to "Inline search filter for all styles panels and swatches", not just list of styles but list of objects within the layer panel. Like Photoshop's layer search.

I use Photoshop quite a bit and found that the search function within the layers panel very helpful when I have MANY layers and I need to find a certain item (see image below). Well, with InDesign, I might have only one layer but TONS of objects in each. So a search function would be incredibly helpful in finding that object.
