Admin API for remaining instance customization chores
We are on the path to finishing Pleroma backend configuration via database and AdminFE, but there are a few things that have not been addressed yet:
- Defining your instance ToS/rules
- Instance logo / background
- Default instance avatar
- NSFW image placeholder (if we don't entirely remove it for a blur)
- Instance thumbnail
- Instance panel
All of these should be customizable via AdminFE, but we will need backend API support to make it possible.
