I feel bad complaining about it since I know people have worked hard on developing features they hope will be useful for users, but it’s not something I use or will look at all. It’s not that it’s ugly (everything in the app looks great except maps) but it doesn’t really offer me additional information with the sort of spending/topping up I do i.e. just top up the minimum and replenish whenever I need it so my balance usually exists between £10-200, the fluctuations don’t really give me info (I use the targets bit/search if I want to know more transaction info).
I saw the thread @alexs shared about it showing more useful info for overdrafts and predictions in the future, which I’m sure would be much appreciated by other users, but again, I won’t use it 
like I mentioned earlier I don’t scroll through it to see what I spend everyday and scrolling through it directs you to the same date a month before so you can’t just stop on a random date, so either way I have to scroll up/down.
But I don’t want Monzo to do away with it for everyone just because a proportion of us don’t use it, so I thought the ability to toggle it on/off would be nice. But like you say introducing lots of settings could make the app really confusing, so I’d say it’s something of a "nice to have. If it takes up too much time/resources, then I’d rather that be devoted to something else.
Talking about what we don’t use/like can be useful anyway so they can just take our feedback into account and improve things for smaller phones etc. so it’s not a wasted debate!
