Drag a preset to an empty space on the timeline creates an adjustment layer.
I have a suggestion that I believe would be a great improvement to quality of life!
Imagine a scenario where you have several effects and presets that you use frequently, but generally, you use them in Adjustment Layers.
In the current moment, we must create an adjustment layer, drag it to the timeline above the desired layers, then drag the effect or preset from the effects panel to the adjustment layer.
It's a process that works, but takes many steps.
Now imagine a much smarter scenario: Instead of doing all the initial work, you would simply drag an effect or a preset to the timeline! If the cursor is above a location that already has an element (such as an A-roll, B-roll, Image, text, or anything), the effect I'm dragging will be applied to that element, as already happens currently, BUT, if I drag it to an empty space on the timeline, an adjustment layer will be created automatically with that effect applied! It would be extremely simpler and more practical for repetitive workflows!
