- Add missing treePush(id) to complement treePop()
- Add basic functions to access ImGui's state storage. Limited to booleans for now with automatic ID scoping.
- Fix ui.invisibleButton() requiring an explicit flag parameter even if empty

- Small delay before displaying button tooltip, better matches the rest of the UI
- Consistent font choice with rest of UI

- Ensure the tab function receives a reference to the self argument
- Reload only the actively selected tab when pressing Ctrl+R

- Allows taking an existing table value and making a copy with some values overridden
- Primary usecase is "inline modification" of a plain table (i.e. not a prototype or class instance)
- Make table.merge() and table.append() more efficient by only checking validity of the predicate once

- Add helpers to iterate a table and return the value with the greatest or least score according to the passed scoring function along with the "winning" score
- Add constant-time class inheritance lookup via cached inheritance map
- Fix erroneous use of table.append() instead of table.merge()

- Add type information to Event.Register
- Add additional method prototypes to Ship.meta.lua
