[FEATURE REQUEST] - Put Trades on Hold

[Tsekeflime]

Is your feature request related to a problem? Please describe.
When mapping or fighting a boss i like to put my trades on hold with a message like "Currently in a map. Do you want me to whisper you back when i am finished?". At this point i would like to have the option to turn down the opacity of the notification panel so it doesn't block any view on the screen.

Describe the solution you'd like
A solution i'd like is having the option to hide the window when using response buttons. And only show window again when hovering over the invisible window or when another trade whisper comes in.

Describe alternatives you've considered
Instead of only hiding the window to have the option to change between opacity while on 'hold' mode. Or to minimize it into a smaller window.
