CTA buttons color

[ZIPender]

Hello,

I got feedbacks of my users saying that "rendre les boutons play restart et stop plus visible ce serait bien" -> "making the play restart and stop buttons more visible could be nice".

That remarks is because currently the only indicator is the white logo at the center that greys out a bit. the whole button being darker when not clickable would be better. at least as an option

I agree! I'm considering doing a semi-overhaul of the power button styling. I'll definitely take this suggestion into consideration for that.
