The reason that Habit and To-Do are capitalized in HabitRPG is because of how they're used. Outside of HabitRPG, they're just common nouns, so they're lowercase. But in HabitRPG, they're being used as a title for a specific kind of task, thus requiring capitalization. It's like the word "auntie" in the sentence: My favourite auntie is Auntie Sally. The first "auntie" is just a common noun, but the second is capitalized because it's a title.

Another reason they're capitalized is because they're no longer just general concepts, but specific concepts, making them proper nouns.

Cron should probably be capitalized. It entirely depends on how the developers intend for it to be used. Is it solely used to refer to the scheduling software? Or is it a metaphysical concept and being used as a fancy synonym for "daybreak" or "dawn". Even if it's the latter, it should still be lowercase, unless it holds large significance (and in HabitRPG, it does).

Inventory still should not be capitalized. Market and Tavern, while tabs in the interface, are still both locations in Habitica. The Guidance page lists "party" as being always lowercase, and "party" is on an equal tier of the interface as "Market" and "Tavern". Therefore, "inventory" should be lowercase. It's not an actual location, and being an interface tab doesn't automatically give it capitalization.
