Warning :

presets are not finalized.english preset is not categorized so its hard to find to rename.
If you create your custom preset from scratch Please send us ktListAndRenamePreset.dat file .I will add preset to preset directory with outhor name.

Description :

The Most taking time is renaming (joints,controllers etc...) for riggers.
This tool renames piles of controllers,joints ikhandlers etc on the fly for you.
Once You created (or use ours)preset you dont have to re-rename aggain and again from outliner.Just go category and click to rename of joint ikhandle or constrain... 
And you have now a standart to rename everything else too.(not limited for rigging. but every other nodes)

Usage:

source ktListAndRename.mel;

How to :

Select joint,goto ktListAndRename,filtername what you are looking for.and click on the filtered list.
That is it.it will rename what you selected on the fly.

You can customize or create your own Standart Names and Presets.
To Create Your Own From Scratch.delete our dat files
