I agree that something needs to be done to improve the Local Adjustment Presets list.
I give my own presets a numerical prefix so they at least sort in some type of order that suits me.
And the 'installed defaults' occupy a major area at the top of the list that then requires scrolling down to my user presets.
And there are a few useless default presets that do nothing!
'Exposure' does nothing (that I can see)- no sliders set!
And what does "Color" do?
