Stupid hierarchy problem!!!

OK, so here’s what happened, I accidentaly pulled the hierarchy with the mouse over the WHOLE DAM SCREEN, I SWEAR it happened under 1 second, I WAS intending to move an object from the hierarchy, and in fact, I grabbed the hierarchy, and now it covers my whole screen.ANd the arrow to resize again the hierarchy, DOESN’T show up, here what it looks like, HOPE THERE IS A SOLUTION, or else I’ll explode.Thanks in advance, it looks stupid, I know, it was A MISTAKE.

Nevermind, fixed, here’s the solution in case that others may encounter this too, on the top right corner it’s a small icon, and if you click it, there will appear an option menu, with the option maximize, click on it, and it shall return to normal

Good you found the solution, it happend probably because you were pressing the SPACE key

Or you could have just clicked on layouts and then default in the menu that dropped down
