You can use a Kit in this pocket, as well, although I usually carry the Kit inside the main Synapse pocket, for the reason that the Kit works well for holding items that use the wider base. This can be used to hold items that would otherwise roll when set down, but can also be for items that are oddly shaped. In the latter case, they wouldn't fit as neatly into the Synapse front pocket, since the base of the Kit is wider than the depth of the front pocket if you don't "scrunch" the Kit slightly when putting it in.
I don't use the Snake Charmer in the front pocket, again, because for most items I would carry in it I'd have to scrunch it a bit to fit it into the front pocket. I know that some people carry a Shop Bag in the bottom pocket, but I carry a Small Shop Bag in one of the front side pockets.
