I BELIEVE THE ADDITION OF THESE PROPULSION SYSTEMS WOULD TAKE THE GAME TO A WHOLE NEW LEVEL AND PERMIT THE CREATION OF CRAFTS BEYOND OUR IMAGINATION! It would also be SUPER awesome to mess with!!!!!

-more customizable and thrust vectoring jet engines

-retractable helicopter rotors/propellers

Basically, you could Launch launchpads into space. For example, you have a base on Smars, and want to do missions there without having to launch them all the way back at Smearth. Well, you could send a Lander with a launchpad on it. Maybe it folds up to save space. You land that on your Smars base, and you now have the option to start there instead of on Smearth! If that seems to OP, then maybe you need to mine resources or it costs ingame money to do it. Another example: You have a space station around, Smaturn, for example, and you want to add modules to it, but Smaturn is far away from Smearth and it is not easy to get a space station module from Smearth to Smaturn, especially if it the module is big! What you could do instead is dock an assembly port to the station, which would work the same as the portable launchpad in the last example. You get the option to start at the space station instead of Smearth! You then can assemble your new station module AT the station instead of all the way back at Smearth! Extraplanetary launchpads would be an awesome addition to Simplerockets 2 because it would be efficient, and fun! (It might work similarly to the Extraplanetary Launchpads mod for Kerbal Space Program!)

I have perfected landing an orbital booster back on Smearth in SR1. Technically it's the entire rocket because it needs the command module but besides that, it's fairly simple. That is, until it comes to touchdown...

With the legs from the first game, You can't use them on the two largest engines because the engine is either the same height or taller than the legs. Sometimes stabilizing it with RCS works but eventually it falls and blows up. Something that would fix this would be larger landing legs, like the ones on a Falcon 9. It would allow even the largest rockets to land safely.

The linking tool displays id of parts

1. We are using the blind connection method, ie you place the component in a bunch of parts but do not know where you want the part to connect to in the new part (A is the part add in blocks B, C, D, E, F, G, H, I, J, K you want A connected to E but sometimes connected to D or H, maybe D, E, F , G) 2. So this tool will directly display the id of the part and the part id that is connected in the game instead of the .xml file. 3. • Display: open the TLTDidOP tool right-click on the component to display the ids on the board (the blue is on the part to indicate the selection) (red to indicate that the selected component is connecting to the sections) , those that do not show transparent. • Next select (Component connection) in the TLTDidOP table, right-click the component, press Lock on the panel to lock the selected components, left mouse button on the component you want to connect, You can use the right mouse button to hide the part you want to bypass the connection. • After selecting the components that need red to connect to the blue component. This will display the tab of the selected section (press the +) and complete.
2. This is necessary for both SP and SR2. "I have used google translate"
