Auto sum additional weight in entries
It would be nice to have a simple way to automatically sum additional weight added to an existing entry without doing mental math or using a calculator.
For example, currently, if I want to keep a record of the amount of water I drink throughout the day but keep it as one entry instead of multiple ones, I'll have to mentally calculate the sum of the consumed amount and the amount I'm currently adding. If there is a button that works like "+__g to this entry" via right click or edit, it would be great.
The same scenario applies to cooking, such as if you added additional ingredients later.
I know I sound lazy but it's just something that I find annoying and should be an easy feature to add.
