I was about to post the suggestion of having more analytics involved in the vault feature, but a few people already suggested it
Summarised:
- Estimated time for reaching goal, based off of spending pattern
- Function to encourage users to spend less by adding what you spent less (on a category) compared to last month to your vault.
- Show this months and last months spending and how much you currently would save to the vault (= difference between last and this month)
- Option to choose which categories to include in this
