is any chance to show in Skin Shop how many Coins player have?

I use the mod Magic Economics Panel (https://umod.org/plugins/magic-economics-panel) on Umod.  Make sure you already have Magic Panel and Economics as well (you can find links for those on the link above).  This will display the current total on the left hand side.  You will have to change the image URL in the Magic Panel config to https://i.imgur.com/nbEeITS.png to get the "coins" effect (old link no longer works).  Not sure if it just displays the total without the coins if you don't use that image.

i was mean that this will be showed in ShopSkim UI not in main HUD
