Insufficient inventory on one sku for an order with multiple skus, the other skus inventory won't be removed from the order once processed.

Sounds broken! You give us the option to have a notification if we have no inventory when we are processing the labels, there is no need for this action to prevent us from shipping an order with no inventory shown.

If we have 1 sku out of the whole order that doesn't show inventory in the system, I will just over ride it if I know we have one in stock or somewhere I can use for the order. I've been doing this forever. Come to find out any order that has 1 single sku with insufficient inventory, the whole rest of the inventory won't be removed either.

A lot of the SKU's we sell are actually kits of several different items bundled together (example - 200 current comic book bags and boards). Given the current limitations of eBay/Amazon/Shipstation, we are forced to create mutant SKU's for kits like that (for example, this SKU might be something like 2-PACKS-CUR / 2-PACKS-BBCUR, which means 2 packs of current bags and 2 packs of current boards). This isn't the best way to sell kitted items. Most good inventory systems allow you to create a "bill of goods" that will show up underneath a kit SKU. For example, this would show the master SKU (200-CUR-B/B or something) and underneath it would show each line item in the kit separately (2x CUR on one line, and 2x BBCUR on another). This makes it much easier for order pickers who are unfamiliar with the product to pick pack and ship orders. If ShipStation could implement something like this, it would really help.
