Why not? What do you think about it?
Excellent idea, like an editing bin !
Propose this on: https://blender.community/c/rightclickselect/
This proposal you posted here, makes total sense.
This way you are storing poses in an NLA track?
If yes NLA is supposed to be for full animations. To save poses we already have under object data properties for the bones a Pose Library to save poses. There is this plugin to add images to the pose library.
Looks useful, try in the Outliner GSOC Discussion and Suggestions, the browse action and the new button should be in the top bar of the NLA to me, maybe the active strip and action clip menus too, just like in the actions and the shape keys editors, I maybe report it as papercut, idk if they are still using that thread.
