When on desktop, if a card is selected or opened, the tabs on the left will automatically open to a relevant tab based on a tag assigned to the card, and the focus of the left side bar will auto-scroll away from where you are to where that tab is. This is incredibly annoying if you are trying to organize several cards and tabs and the area you are trying to organize continually gets changed.
Tabs on the side will also automatically open whenever a card is selected. Having the ability to turn this off would be very nice, as this results in tabs being opened ad nauseam and makes scrolling to an intended tab later a cumbersome chore given that you have to sift through several tabs.
