This will be long but i will tell what should be added as major parts:

• added hollow fuselages that serves for plane's internal stuffs, such as for passenger planes or even cargo planes. Of course it can be customized like any other fuselages and even capable of added seats as they wish. For further stuffs, hollow fuselages also can be cutted from full circle to 90%, this will be useful when in creating new cockpits.

• Bomb bay doors which can be done in various customizations such as edge shapes (curved-smooth-hard-circular-custom) and can be acted like how normal fuselages are.

• For additional wing issues, we may add flaps or even airbrakes for airplanes

• Added canopy fuselage, which intended to be seen at outside but can be visible when at inside, acted as real canopy for realism.

• Added newer gizmos, such as arrestor hooks for carrier landing, customizeable airbrakes, Retracable or static pontoons, and others

• For weapons, We can add variety of bombs, such as guided bombs, Cluster bombs, Fuel Air Exploding Bombs, etc. For AAM's we may add more missiles, including using Heatseeking missiles and salvo fire missiles. For AGM's we may add salvo fire AGM's and more. For additional types, we may use Radars and ECM with their pods to experience even more realism in combat mode. Also i will recommend to have custom reticule in each plane and have bomb drop reticule if we want to drop the bombs

• For landing gears, we should add further customizations in resizeable wheels for rims designs.

• For engine use, i may issuing to create reverse thrust systems for all possible engines.

-For further ship building capabilities, i may issue creating a seperate ship hull that could acted like how fuselages are but designed to be floated at waters. Also, this may be useful in creating more guns related to ships or even more functions with AP and HE shells use

• As for collaboration with Simple Rockets 2, i may issue to Jundroo group to Combine and capable of transfer data from SP to SR2 or vice versa, also in further updates, i recommend that Simpleplanes can be also launched at space, similar as in SR2 but with some configurations that may be helpful in mobile phones

• For mobile user issues, i may advise to optimize performance to smoothen and clearly capable of accessing 600 parts or even maximized length for less lag even with many weapons on board.

That will be all from myself, hopefully this will help for updates and more.
