Nothing too clever, just a few things I made for my own Arcs experience, YMMV.

1. Player Tray: one of the main "issues" I had with the insert for Blighted Reach is the way that the player trays are partitioned meant the bits would mingle over to the card side of the tray. This isn't actually an issue, but I liked the idea of keeping them all on one side. These fit in the existing tray, mostly fit the bits with a little bit of effort, and lift out for...

2. Big Box -> Small Box quick change. The box for Blighted Reach is a big customer, and for playing a non-campaign game can be a bit much. Wanted to be able to pack the Core game back into it's box without too much hassle. Half-ish height card box for Setup, Action, Lore and Base court deck is easy to grab out of the well while not looking too out of place. Leader box is more noticeable in the insert, but that helps it stand apart from the Fate overview cards. Then Map, the trays above,Player boards and the base game tray from BR. I can switch over from one box to the other in about 2 minutes- not actually sure if that's faster than without this stuff, but it feels like it? It's possible that some spacers may be needed for the small box end for heavy travel, but so far Shelf to Table this has worked out.

3. "Card" holders for Fate tokens. The other issue I had with the original insert is that the seeming best way to store/sort the tokens are baggies. We love to avoid a baggie if we can. I will admit that the tolerances here probably need revisited- possibly a bit too tight on the circular tokens, and a bit too loose on the octograms. With sleeved cards, though, everything in my copy is staying in place.

The walls on these are a little bit thinner than I normally prefer, in order to fit in the existing Insert's space. So far no issues, but something to keep in mind
