- Updated BUGS.md with new issues related to selection bounding box, touchpad panning speed, and zooming behavior. - Enhanced PROJECT.md with detailed specifications for touchpad controls, recent colors in the color picker, and a status bar for project information. - Modified project.godot to update compatibility version to 4.7. - Added a status bar in stickman_editor.tscn to display cursor coordinates and snap status. - Updated body_part_panel.gd to handle recent colors and cursor detection over drawing areas. - Enhanced stickman_editor.gd to manage cursor coordinates display and recent colors tracking. - Improved whole_stickman_preview.gd to render selection gizmos on top of other parts. - Created master_rig.tscn for the stickman rig structure with bones and IK targets. - Developed master_rig_builder.gd to automate the rig building process with remote transforms and IK modifications.
