Recently moved to Delphi 10.4 and I get far too many Units showing in the central pane of the IDE. (It didn't happen with XE.)
My main project group has up to 15 programs in it.
I can remove each unit manually from view in the central pane, but if I close the Project Group they all come back again!
Is there a setting I can use so a large Project Group only opens with 1 Mainform of the selected Project initially showing (as I had in Delphi XE)?
(The reason for multiple projects is they share lots of common features and form a toolbox suite.)
Grateful for advice.
