Greetings,
The thing I was looking for years, and wasn’t able to find implemented is the ability to create rules for incoming/outgoing transactions.
Example: “On Incoming transaction to [account_number] if [received_amound] >= 100EUR send 10% of [received_amount] to [another_account_number]”
This kind of rules could really help people who struggle making savings and the ones investing on a regular basis. The advantage over traditional recurring payments would be that the person should not worry about having money on a particular account at a defined date. You basically can configure the rule, and throw all the dates out of your head.
If precise date is needed, it also can be included within the rule engine.
I hope this idea will find it’s way to being implemented someday. 
Thank you!
