Thanks for the suggestion!
We will likely implement a way to organize the order of inventories inside components.
Your screenshot however shows the inventories on version page, and not inside a component. Do you mean it should be possible to order inventories (products) on version page also? @galina

Thanks, Eirik, on both pages it could be an excellent option. But mainly I mentioned the component menu because I've made a component first and then moved it to the project in my working process.
