When constructing my missions in the editor, I constantly found myself switching between the editor and the Virtual Armory to make customized load-outs. Instead of memorizing classnames, using the Virtual Armory helps mission designers to create custom load-outs with ease and efficiency. This would particularly useful with mods where a user might download multiple types of mods and mix content between them.
Currently, we to load in the Virtual Armory, design the unit, save and export, load in editor, load mission, and paste code into init field of unit. Adding a button to access the Virtual Armory from the editor, and when exporting/exiting, it would return you to the mission which you were previously editing. Such functionality would simplify that process down, and reduce load times for mission designers.
