it is inconvenient to work with the "layers" tab

1. Hello, the thumbnails in the layers tab are very inconvenient and uninformative. In these squares, in most cases, it is impossible to discern the appearance of the object. If you enlarge the thumbnail, the ribbon becomes inconveniently large.
2. Why not make it so that this tab automatically scrolls to the element selected on the canvas. When there are few elements, it is not difficult to scroll the tab, but if there are more than a hundred, you have to scroll slowly and slowly to notice which element I have selected.
3. White elements do not have thumbnails. Is it possible to make them somehow displayed in the thumbnails, at least a black super-thin outline
