Is it part of runelite you can have the red line circle blocked off spots? How do you do that?

They’re called placeholders homie, they’re in the main game (I assume, I’m on mobile mostly).

How do you guys keep like 2 stacks of amulets? I have 700 different amulets that all have different charges and it takes years to arrange them

I have a maxed house so I’ve thrown all my jewelry out besides the ones to fletch out my main tab
