This is the first version of tags. I hope it will become more sophisticated in the future. Please bear with us!
The reasons my team haven’t pursued this are complex. In essence it would exponentially increase the difficulty of building many of the upcoming features we have (thus delaying them unnecessarily). It could also, as Hugo explained, cause confusion for customers.
The ability for us to reliably categorise all incoming transactions is extremely important, and not to be underestimated. Custom categories could add significant complexity and ambiguity, and significantly hinder our ability to do automatic categorisation on your behalf. We are worried that this would weaken the usefulness of some features (including some unreleased ones), and compromise their accuracy.
We think it’s better to have a core suite of categories (which we are adding to!) and take advantage of tags to allow you to group transactions arbitrarily and get custom insights that way.
Hope this makes sense.
