Reset values to default
Sometimes we want to change some attributes (on a shader, texture, node - in short: on everything that can be changed) to see what the result is gonna be. However, it's not always that this result is what we were expecting and when we decide to come back to the default values most of the time we don't remember what the default numbers were.
So, it would be GREAT if there was an option to reset the values on the tab that we see when we press the right mouse button on something (exactly there where we see these options: "Create New Expression; Set key; Set Driven Key; Create New Texture; Lock Attribute"). The first option, for instance, could be "RESET TO DEFAULT".
With this feature we will no longer be afraid of changing something and not to know how to go back to the default value.
