Could the Grid template be made into a slider function? (like a 3 split hero?) This looks quite attractive with an image cursor highlight and arrow icons. One column on mobile is fine (maybe 2 option?). Currently the only option for image slider is the large banner slideshow which isnt always desirable on desktop due to the full length stretching etc. Example, 2nd template under the slideshow at top.
Maybe the grids can allow videos too to be extra fancy? :-P
