UX suggestion: Indicate on score atonal key signature
C major and atonal cannot be visually distinguish easily, leading to tricky problem esp. instrument change in transposing instrument see this post
Could use a cross or invisible representation similar to page break

You can certain add a symbol from the Symbols palette (press "Z" to display), but the question is, would musicians understand what you mean? Confusing as it might initially seem, no key signature is the standard way of indicating this, so it's what musicians playing this music are already accustomed to.
Not sure what exactly you mean regarding instrument changes. There's a lot going on in that other thread so I'm not sure what exactly you are referring to. For me, though, if I have an atonal key signature then add an instrument change, it remains atonal as I expect, even if the transposition changes.

Probably the OP means an 'invisible' (grey) X mark in place of the (non-)key sig, similar to how it looks in the palette. So something that won't print, just tell the MuseScore user the diff between C-Major/a-minor and none, and not confuse the musician

Ah. Could be tricky, because you don't want it to take up space. Meanwhile, when in doubt, Alt+Left/Right will traverse your score element-by-element and the status bar will report when a key signature is present and what type it is, whether visible or not.

@Jojo-Schmitz: Yes something like that.
@Marc Sabatella: Thanks I didn't know that.

Invisible items are not supposed to take space.
But then indeed they may vanish under other and visible things

Yes that is what I meant about it being tricky - the most straightforward implementation might not be as useful as people would want.
For that matter, it could sometimes be useful to see the C major key signature. MuseScore has a funny way of handling those - sometimes they are present in the score, sometimes only implied by the absence of a key signature.
