notes say:
14 feat: UIDrawable sf::rect_something AABB(), bool visible(), and bool hidden for toggling visibility or skipping rendering

bool visible() - returns False if out of bounds of the current view, or always True if the UIDrawable is hidden.
bool hidden - internal member on the parent class to track visibility
virtual sf::some_kind_of_rect AABB(), a new required method on derived classes to get the screen coordinates of a thing.

Upgraded to "Major Feature" because I suspect it needs some references (".parent" or the like) to recursively climb back up to the root and get add up offsets.

non-visible Drawables can't be clicked or rendered.

Status: Fully implemented

visible property exists on UIDrawable (src/UIDrawable.h:81)
Template getters/setters in src/UIBase.h:109-123
opacity property also implemented (UIBase.h:125-150)
All UIDrawable types (Frame, Caption, Sprite, Grid, etc.) inherit these via UIDRAWABLE_GETSETTERS macro
Documentation is complete

Already Implemented

This feature was implemented as part of the Phase 1 UIDrawable improvements.

Current Implementation

visible property on all UIDrawable subclasses (UIDrawable.h:81)
opacity property for gradual visibility (UIDrawable.h:82)
Template getters/setters in UIBase.h:109-163
All types inherit via UIDRAWABLE_GETSETTERS macro

frame.visible = False  # Skip rendering and click handling
frame.opacity = 0.5    # Semi-transparent

Non-visible Drawables are not rendered and cannot be clicked, as specified.
