Is this feature not available in the new version?

Is this feature not available in the new version? In old version, I can use this feature to easily display the content I want by searching and clicking, but in the new version I can not find it

With me, I use Ctrl + Shift + C more to open this menu… Click on the text of rem then press the shortcut…

This behaves differently now with hiding being different from folding and most hover effects removed.
If you have actually hidden children then you get an indicator that you can click:

Right clicking the bullet or toggle button is not bound to something useful yet. Maybe we can add that menu for toggled children there.
Otherwise you can show the menu always using the View Hidden Children slash command.

But note that if you show a just toggled but not explicitly hidden child the other toggled children become hidden to make that possible.
