Button to bring slave back online should be reworded. Currently, when taking a node offline, the button reads as follows:

"Mark this node temporarily offline"

But, once offline, the button to bring back online reads as follows:

"This node is back online"

When, I first read this, it gave me the impression that the node was in face online.

It would be nice if the two messages where consistent. This could be done by changing the text to bring online as follows:

"Mark this node online"

or

"Bring this node online"

or equivalent message.
