The batch tools buttons for members are not named properly.
The buttons are named "Select xxxx" etcetera. However, this is not (afaik) what they do.
They do not "select" (as in the search), in "batch" they "set".
The heading ---- Batch-Tools ---- should more informatively say, ---- Batch Tools - For selected/checked members, do ...----
And the the buttons should be labeled "Set xxxx to..." etcetera.
Then it will be more clear what will happen when the batch button is activated.
(Btw, I also miss an opportunity to set any field to a certain value.)
