Is there a way to mass remove from treasure chests? I should empty out a TC with over 2,000 items and with the huge lag and all doing it by hand one by one... Oh gosh >D

unfortunately there isn't. you can hold down the control key (or command key on a mac) while you click the X on each item to open the 'refreshed' page in a new tab so you don't have to reload the page for every single item. control-click a bunch, close all the new tabs, control-click a bunch more, and so on. of course with over 2,000 items this will still be very tedious and time-consuming. a mass remove option is being considered, though, as mentioned in Organizing & Mass-Removing TC Items.

I miss when "select all" and "remove all" were the norm on websites, instead of having to be requested.

Aw man! I do hope it'll be an option some day. But for now I'll try out that method. Thanks for the tip! c:
