Yep. Would be great. I hate hidden information.
Suggested something like this a while ago. For some reason I didn't include Missile health however. No idea why.
Sure, low/high maneuverability can be useful, but degrees/second, acceleration, top speed, etc, would be moreso.
Plus, naturally, with modders on the loose, custom additional stats would be nice.
Suggest ability for any and all weapons to have their tooltip data for each stat be overridden.
Suggest additional Tooltip Elements
-Volley Size
-Volley Damage
-Volley Flux-Cost
-Volley Duration
-Volleys per minute
-Recoil Default Arc
-Recoil Cap Arc
-Recoil Increase Rate
-Recoil Decrease Rate
-Projectile Speed
-Missile Acceleration
-Missile Top-Speed/Friction/whatever
-Missile Targeting Description (Engines for Salamander, for example)
And ability to add any category you dang well please, such as Chain-lighting Jump Radius, or Damage per second from Acid.
