Robert,
The Home>Health>Conditions page actually lists as many symptoms as will display in the column. Granted it is not very wide and if you have more than will fit, you should see an ellipsis (...) displayed in the column text. Please see images below and note that we added two symptoms for the pregnancy condition (leg cramps and nausea and vomitting). Both are displayed in the conditions list page.
It seems a good idea for us to consider making a number of options available - as part of customization - for which columns can be displayed. If this were to be enabled in future versions, you'd then be able to select the comments column, instead of the symptoms column.
You are correct that the current order of display for conditions in the Medical History Summary is somewhat confusing and we will try and fix it for our next release.
Thanks!
