I would like to have the ability to add simple money tag to track costs of projects or shopping lists. It could work very similar as the time tag, but instead of time, it counts money (or any numbers). For example the syntax could be following:
milk €0,93 cheese €7 car €10k selling the old car €-3k
This would show the sum of subtasks in the Shopping list’s row. It is fairly irrelevant which currency symbol you use, or is it a currency symbol at all. All it needs to do is add and substract numbers.
