Makes sense, esp. for PBS due to its nature. I'll look into it sometime!

Good point, but I agree, hard to judge what's better. As we are
defaulting to max. 16 GiB (for PVE), it's a rather smaller range, so MiB
makes sense IMO.
Although aligning it with all the other inputs, which are in GiB, makes
sense too. As well as inputting it as GiB float should be precise enough
for any case.
I will definitely keep it in mind for the future.
