The buttons at the top of the Events list view/main Events page are not in the same order that they are on every other List in NXT. Those are usually Add - Search - Column - Filter. Events are in the order Add - Filter - Column - Search.
It's mildly confusing and disorienting to have the buttons in a different order. I keep forgetting that the filter button exists beause I'm looking for it at the end of the row. Also, "columns" is written out but it usually isn't, so I keep instinctively clicking on it instead of Filter because it's bigger and more attention-grabbing.
