Allow negative amounts e.g. for refunds

Hi, I use negative amounts in situations where I receive a refund for the entire project group. E.g. I pay for some electronic device for the entire group. That expense is split among everyone. Now the device breaks and I collect the refund, which, as 'Income' is again split back among every member.

Currently this works perfectly in Cospend, however the interface labels the amounts field red if a negative value is added. Apologies, if I am reopening a discussion about that (I could not find any), since the labeling behavior appears to be intentional.

What do you think about such a scenario? Could the amount check be less strict?

Best regards
