So, you know the most fun parts of building a rocket? design and build the cargo, maybe like a rover, a landing probe, etc... BUT, what's the boring part? configure the landing legs and parachutes to do the mission, so there should be a few in-game configurations for them to help us. So maybe there should be some to help and spare time.
Parachute Configurations (Change radius, Inflation Air Density, Max Deployment Speed and Deployment Air Density):
Martian: In parachutes, this would adjust the deployment and inflation air density and max deployment speed.
Venusian: Would set deployment speed, and deployment and inflation air density to make a safe landing speed.
Lunar: You know? Titan-like moons, dense atmosphere, low gravity, and set the max deployment speed, air density and inflation air density, to land rovers and probes.
Default: The good old parachute, which would be automatically setted when a parachute is added, in case you would just add it to a Pariot Capsule to land back on Droo.
Landing Legs Configurations (Changes Damper, Size, Design, Deployment Angle and Deployment Speed):
Martian: Would be normal sized, fast deployment speed, advanced design, normal angle and 20 in damper, perfect to land space probes on martian type planets like Cylero.
Venusian: 25% Larger, medium deployment speed, default design, more 5 degrees in angle, and 22 in damper. Designed to soft landings on your average Droo-sized planets with extreme greenhouse effect.
Default: Your default landing leg to land on celestial body, automatically selected when a landing leg is added.
Custom: The part enters this configuration if you change any of the settings it changes.
Low Gravity: Sets the damper to 30 and changes the length to 30%.
High Gravity: Sets the damper to a even higher value.
Crater: Sets the damper to a lower value, and deployed angle to a higher inclination.
Oceanic: Replaces the botom of the landing with a buoy, perfect to land on oceans, like Taurus', Nebra's and Droo's.
Just saying, i don't know you, but i find it pretty annoying to see the planet's atmosphere dennsity on PlanetStudio or in the Fandom Wiki to set the parachute, and also adjusting the landing leg is a bit slow. So MAYBE, just MAYBE a few in-game configurations should be in JNO to help us spare time.
