Fast_Frame_Scrub_Basic is a lightweight Blender add-on that lets you scrub the timeline directly from the 3D Viewport, Node Editor, or Graph Editor using a hotkey and mouse drag, without opening the Timeline editor.

PuppetTag adds readable, editable rig labels directly inside Blender's 3D View. It lets animators and riggers understand complex armatures without changing the real bone names, using display aliases that leave the original data untouched.
