[feature request] Minimize to task bar

[lmills87]

Would be nice if there was an option to minimize borderless windows to the task bar instead of having them stay in the background whenever I alt-tab. As it is currently I need another program to do this but it seems like this could be easily consolidated into BG.

And then close BG and it will work without being in the way of your alt tab
