You currently have to have a goal amount. It would be nice to just have money set aside each month for savings (like an emergency fund) with no goal - just deduct this amount from my spending plan each month.
@HSC That's a great suggestion! You have my vote!
To start, this could be a very basic feature! Just a checkbox or empty field to indicate open goal.
A future enhancement could be modifying the reporting toward the goal. Instead of showing progress toward the goal amount (which doesn't exist), it could show a tracker of recent scheduled contributions and whether they were done (with statistics), and a graph of growth over time. Views like that would turn this from just an "open goal" feature, into something that could be an insightful and helpful way of monitoring progress.
The ability to not set an end date in the savings goal is a very good example of how simply this open savings goal feature could be implemented:
