• it was harder to roleplay some more complicated concept, like reusable rockets
• writing "Test", and then removing autosaved "Test" copy of the vessels.
• Switching append/prepend to queue require exit to KSC and go to the settings.
• It was not possible to add several vessel with the same name to queue

So I reimagine the mod, and now it's even less restrictive:

• restore stock Launch button action (disable any checking there)
• add 3 new separate buttons in the Editor: [Simulation], [Prepend] and [Append] planning to the quere (if its enabled)

So now launch button doesn't check anything itself and you can launch reusable rocket at ones, you don't need to write "Test" since there is spetial button for the Simulation.
Also you have separate buttons for Append/Prepend (disableable), and it is possible to add any amount of equally named vessels with a same name.

• enabled queue by default on all difficulty preset
• enabled by default SpeedUp by passing Years (5 years is default)
• disabled speedup by Rep by default.
  It is very easy to get >700 at early career with default Rep settings without leaving homeworld SOI, so it wasn't having much sense.
• option for autoremove finished planning timers on launch.
