Currently both the list and grid view have their advantages and disadvantages, especially since the sudden loss of responsive columns of the list view I find myself switching back and forth. In some occasions the list view is still more compact, but as soon as there are many items in one category - i.e. colors - I feel forced to switch to grid to avoid endless scrolling.

To counter this and add customizability, how about being able to select the view mode per category? For example grid for colors, list for components or vice versa - just the way your project needs it best.
