If open a previous created draft e-mail on my android phone.
Than close it. Proton reports the draft is being saved. and gives an option to negect it (negeer in Dutch)
While i didn't change anything to the draft it seemed nonsense to save it. So in a impuls I clicked 'neglect'..

And now my draft is deleted.. with all info I needed badly.

Why is this button there while saving? Why isn't it called PERMANENTLY DELETE draft??

'Neglecting saving a file' is not the same as deleting the original. Not in any program I know.
Also not in the proton desktop version.
Why is the draft not put in the bin? So it can be retrieved.
