I think if you want an “overview of my whole account and only classes money in and out as money that has actually left my account or come in from external” then you need to select your account and all pots from the filter menu.
The balances and graphs can look a bit weird when you deselect pots, I think I sort of alluded to this issue in my post here: Better way to balance your money in Trends is here ⚖️ - #284 by Lewis_P
My proposed solution was to add additional filters to make it easier to select or deselect all pots, perhaps with some tool tips to explain what the presets will show you. I guess what you’re asking for here, is more about being able to hide/exclude spending categories (such as tranfers) from the trends and balance figures. It might work but I think its going to get messy and confusing pretty quickly.
