How to let a tab-subpatcher float above other tab-subpachers

Hello to C74-readers!

After a few hours of testing I have to write this...

I have, probably a very simple question about using the float-windows-option in a (Global) patcher that was multiple tabs.

Here is an example:

The Global/main patcher has A B C D E tabs.

On the D tabs there is a subpatcher (also shown on the parent tab) that I want to activate from A B C orE tabs only as a float-window with a (very important for me) truncated view (lesser options). This is because I wish to left some minor navigation UI's and spare some space.

But I also wish to tick on tab D and view the full subpatcher as like the other ones with all its UI's. This view should be embedded in the main patch window (sim. to A B C and E)

What I expect from my pacht is to control the D-subpacht from different places of the Global patcher (sometimes with lesser functions) but always wish actual settings viewed/edited. Please take a look at the example attached...

That's my question!

I did try to put the D subpatcher inside a bpatcher and place that bpatcher into the D-tab itself, but bpatcher abstraction does not understand commands: (window flags float, window exec) and (window flags nofloat, window exec), so it doas not float.

Also I tried to left the D subpatch on the D tab and using to send the same commands to it's own [thispatcher], but, strange enough, this forces the Global patcher to float and not my D subpatcher! Only when I deactivate option "Show on Parent Patcher Tab" on D-patcher's inspector, the D-patcher can float. But that is not only I wish.

Thank you for the patience and your response in advance,
Best wishes,

Alfredo
