The fire emoji is the forecast detail script. It gives a fire emoji in your reviews if there are items to burn and a bunch more cool additions to the forecast
(The golden button is golden burns which gives reviews the golden color if you’re getting items to burn and colors the burned section the golden color in general
EDIT: I’m a dummy, the golden button is included with forecast detail. Golden burns only gives the gold to the section that shows how many items you have on each level, and to the level 60 people in the forums).
I’m not sure if there’s a way to find out how much time I spend on wk with some script, but I think usually spend 5 to 10 mins on each review, and I do two reviews per day spaced out by 3 to 5 hours! So 10 to 20 minutes? I never counted my time but I can do if you’re interested!
