Imagine you could make your own software? Please go ahead and describe what you would like us to develop for you. We will take ideas into consideration when they start gaining a few votes from other customers. You have 10 votes at your disposal. And once brilliant ideas you added (or just voted for) are announced as implemented - you will get your votes back.
It would be convenient to have the times reported as headings at the beginning of each section (activity, fluid, medication eg.), so that when there are many treatment lines the time can be easily checked.
