I don't see a link to the presentation; so, I'm shooting blind here: But, I'd like to see the ability to automatically save all the settings needed to make the print, once it has been deemed acceptable by the user. This file could be placed in the same directory with the print, with a different extension. This should be optional, so it can be turned off. By doing this automatically, based on the user's response, this would ensure that should the object need be printed in the future, it will automatically load this preset, to ensure they get the same quality as before. It could be enhanced, so say if the filament plugin has been updated by the manufacturer, or they choose a different type filament, it can accept these changes too. Whether these would show as potentially different profiles for the print upon startup for 'that' print should also be considered.
Personally, I've started saving profiles along with the print object's .stl file location, or type of print object to ensure I don't have to retweak profiles too much. For example: a setting for making fine resolution jewelry only a few layers thick; or when building support materials, which don't need the fine tweaking, and can have different infills and/or skirting if any.
