I'm shipping a managed package that will include a lightning app with a few lighting components to configure some "master org level settings". I have an external application that will need to query these settings as needed. Most of these settings are simple booleans and strings. So the lightning app should have access to them and they should be available though the web API.
Where is the best place to store these settings?
It looks like Custom Settings could work for this purpose but wanted to make sure this is the best option as the data types seem a bit limited (strings limited to 255 chars for example).
