Any ideas?

Are there any mods that remind you to that you twr is too low, that you can't reach your given destination, or forgot parachutes? Perhaps it reminds you just before you leave the VAB.

And if so, is there a mod that adds... this audio as the main menu theme?

no, you cannot really tell if you cant reach your destination since you can do everything more efficently or less.

there is a stock reminder in the ship info section while in VAB.

it shows if you have parachutes, ladders, electricity production and more.

altrough you need to check your twr your self, just make sure your craft has it above 1.

theres a mod for editing music in ksp, soundtrack edited forked or something
