I’ve recently found myself wanting to use a performance patch which consists of a bunch of graph-on-parent abstractions I’ve built on both my laptop and a Raspberry Pi with a small touchscreen, and am of course finding the laptop versions impossible to use on the Pi. I figure the best approach is to write a backend abstraction for each, then multiple UIs that I can swap out depending on the situation. 

Has anyone here done this? Would you be willing to share your work or some tips? I started the job last night and I’m having some success, but wonder if I’m missing some really obvious patterns that would make the whole thing more elegant/usable/less likely to fall apart in performance. 

Cheers
