Ability to hide categories/subcats - Mint can auto-categorize those transactions as "uncategorized" instead.
I'm positive you will ignore this request because it seems hundreds of other users have already asked about it, but I'm chiming in again in the hopes that someone on the Mint team will start caring about their users' actual needs.
It is essential to have the ability to hide categories and sub-categories simply BECAUSE Mint chose to create a hundred crazily granular categories. The clutter is completely counter-productive and antithetical to budgeting 101. The hide option is an extremely easy feature to implement. I would rather trxns that would normally be auto-categorized by Mint as any of the hidden categories be labeled "Uncategorized."
Seriously, if you guys don't have any intention of implementing this feature, just be honest and say so, so I can go ahead and quit using a product that doesn't care about its users.
