I just feel like it could be better and not sure why it doesn't maximize available space on mobile. Couple of layout ideas and apologies in advance for the rushed artwork but you'll get the idea.
- is just simply extending the existing window to the top of the screen, thinking you'd get 1-2 more pieces of equipment on screen.
- similar to 1 but moving the bottom buttons up the left of the screen, could probably get 2-3 extra pieces of equipment on screen.
- this is a long shot but worth throwing it out there for brainstorming purposes, what about making it a dual list and having it horizontal scroll instead of vertical. Could be single window by default with an arrow to expand to dual list.
