I agree. Right now we have to do the math separately when things are not evenly split.

It would be great to have a way to always have the remaining balance calculated so if the total cost is 10.-, I put 8 to one person, the other would automatically get 2.

Also it would be nice to have easy fraction options so you can select 1/4 or 1/3 for one person and the remaining balance is calculated automatically.
