What's the point of adding rollup buttons
From WB config can also set for min, max and close, should we get rid of those buttons

, there are 2 actions and 8 settings in WB config, not including use skin setting, of which in SKS5 there are many (seems not in SKS6 yet), in SKS6 you can add 4 buttons, settings are rollup/down, command, context help and always on top, 3 of these are also in WB config, just gives skinners/users more usability of these options by having set buttons for some.
