-- Please add an optional time out to remove the attention grabber from the screen

-- "Unbundle" the closing of the attention grabber and the closing of the chat window

-- When users close the chat window, show a small tab to open it up again.

-- When using your own theme, the controls under transparent area are non-responsive. This may confuse visitors.

-- I already suggested to repalce +/- signs on your in-house control with up/down graphics because it isn't clear that the minus sign closes active window

-- Add an option for situating [contact me] tab on the side, just like your feedback button.
