Navigator and inspector behaviors on Xcode with BigSur

Example on Xcode with OSX10.15 of before:
Tab1: Navigator opened and inspector closed
Tab2: Navigator closed and inspector opened

But after upgrade to BigSur, navigator and inspector can't have different open/close status in different tabs, do everyone facing this problem?
Yes, me too I have the same trouble.
Xcode 12.4 on BigSur doesn't let us configure the Inspector status (open/close) within each TAB.

Actually I can just set the Inspector open/close for all the TABs. And this is annoying especially when I have a TAB open on a XIB file and I need the Inspector open, then I have another TAB open on a code.m file and I need the Inspector closed.

So now I spend a lot of time at opening and closing the Inspector every time I go from a code.m file to a XIB file and viceversa.
I hope Apple address this issue on the next release.

Should I file a bug/request/suggestion to Apple?
