After updating to Quark-r1.5-148, the sorting icons on Iron Chests have disappeared. Before the update the sorting icons appeared on all Iron Chest inventories. It seems the mod has now lost Iron Chest support.

Also when you hover over curtain items in the bottom inventory, it causing a weird red overlay on some top inventories or tables (workbenches, backpacks, Tinkers' tables, etc).

The red overlay appears to be a config setting that I'm guessing is meant for dev use but was unintentionally left enabled: "B:"Show invalid slots"=true" in the config, change to false.

Can't speak for the iron chests thing, but I assume it's because mods are prepping for 1.13 (I had one blow up in my face fantastically doing this).

The red overlay isn't a dev thing, it's deliberate.

Also, this was fixed in 149.

I'm still getting the red highlighted overlays in Quark-r1.5-150.

They remain intentional. Turn them off in the config if you don't want them.

Apologies and my bad, I just realized what it's doing, It's definitely useful, especially with the backpacks (that has built in filters) and I will leave it on.

I also have the red overlay, but can't understand what line to set to false in the config for it... please advise...

Invalid slot overlays.

Thanks... Also, in-game it's under the Quark Config GUI - Client - 2nd page (if there are multiple pages) - Show Invalid Slots.
