Yes! Great ideas! Would it be possible to -at the very least- allow one to enter a bottle feed while the breastfeeding timer is running!?

If there was an option to turn on both the breastfeeding and bottle/supp feeding option at the same time and to be able to pause the bottle/supp whilst continuing the breastfeeding, this would help. Even include a confirmation button perhaps, so when you press the second button i.e breastfeeding whilst the bottle button is running, a prompt question could ask If a suplimentry nursing system (sns) is in use and when confirmed a new icon becomes available? And still record the amount of formula/ebm used.
I hope that makes sense!

Thanks for the suggestion! Can you describe how this might work - would you want to include some info in the breast feeding session that includes the amount from supplementary feeding? I guess you're aware of the bottle feeding option, and you could use that in addition to the breastfeeding/nursing activity to record supplementary feeds, but perhaps that doesn't provide what you need?
