Is it possible to configure Krita to zoom to a location, like in Photoshop? That is, drag over an area on the canvas and zoom so that this area fits the window as much as possible>
Krita doesn’t do that. If you use the Overview docker, it shows a rectangular ‘view hole’ which represents the canvas position/size in comparison to the entire image. In the overview docker, you can zoom in/out with the mouse wheel then drag the canvas view hole around the image If you’re using a pen, you can use the zoom slider bar to adjust the size.
