Armature Pie is a Blender add-on built around two tools for working with armatures. ArmaturePicker, found under View3D > Sidebar > ArmPie, lets you select your armature from numerous objects. You can record filtering settings to a preset and switch back to it next time, and hide other armature objects when you make a selection.
The Solo Pie toggles bone collection solo through a pie menu. Only BoneCollections set as titles, along with their children, appear in the menu, keeping it clean and easy to use. Solo Settings configure both the Solo Pie and the Show Panel, letting you mark a collection as a title and set its icon or name and its position in the pie.
Keymaps are configurable to fit a particular workflow, with defaults of Ctrl + Right Mouse for the Solo Pie and Shift + 1 for the Armature Picker. The Solo Pie can be called for the active object or for a specific object, which helps in cases where the armature can't be activated, such as Weight Painting. Version 1.1.2 fixed a keymap display error. The add-on requires no special permissions and works with Blender 4.2 LTS and newer.
