Option to further increase Asset Icons / Size in general

Essentially I want/need the option to further increase the size of the asset icons (Possibly like the substance 3D assets + and - tool).

I stuggle with seeing the exact textures, even with the size on large - particulary with the texture maps (eg. grunge ect.) as they all look the same. I know hovering over shows the larger version (Which is a much better size) however I find that this can take time to load which is impracticle when looking through hundreds of textures. 

Alternatively perhaps a page on the website or a document you can download with all these maps on it so you can zoom in to find the correct one and then somply search for it.
