These appear to be powerful and may be a good new foundation to build on, but are pretty hard to use at the moment.
I dont know what to name mine, because I'm not exactly which parts of the current view I'm saving, and what will change when i apply one. For example, it saves the sizes of each of my tile views right? Does it do that based on the field, or based on which number it is in the order of the list, or neither? What happens if you apply a preset to a view which doesnt have that field in it?
I think that some kind of customize current view interface would be good, showing you which columns, sizes and sorting are going to get saved. On top of that it would be good if you could tick just certain parts to be saved in the preset. (ie. just save the sorting, or just the columns to include)
