Feedback Inspector window debug setting lost on restart

In Unity 5.x I loved the idea of having two inspector windows open all the time. One with the normal mode, one with debu mode to quickly see other values. In 5.x the mode was remembered when cllosing and opening unity again. Sadly this is not the case for quite a few versions now. Is there any reason this was changed? This is a small detail that makes my life a bit easier.
