I will be implementing a built-in UFOpedia extension, which should:
1. display various statistics for a player (only for already researched/unlocked stuff)
2. summarize/query rulesets for modders (in debug mode, shows all stuff)
You can imagine it as a table, which shows various objects (craft, weapons, armors, aliens, ...); one per row.
It can also show views (i.e. more complex queries) like for example "All weapons capable of inflicting stun".
The first table column will display the name of the object and all other columns will be dynamic, i.e. you will be able to select a bunch of object attributes you are interested in. Sorting will be available too. Maybe also filtering/searching.
Example:
a/ you select a view "Show all craft"
b/ and select dynamic columns, for example "crew size", "hwp count", "pilots required" and "rent cost"
...and a table will be rendered with this data.
Now the question to both players and modders: which objects/views would you be interested in the most?
