On a desktop, I have the ability to create reports with graphs that show a breakdown of the subcategories. E.g. I can open a report for dining and drinks, then I'll get not only a list of transaction, but a bar graph of the sub items -- bars, restaurants, etc.
On Mobile, no such view exists. Clicking into "Dining and Drinks" just gives me a dump of transactions that month. I can't, at a glance on my mobile device, determine what the biggest spend of a subcategory is.
Please add this.
