I have two suggestions for krita very useful if not necessary for the layout: The option Distribute and align not only for vector images but also for raster levels (gimp has them and is very convenient, as well as photoshop); Parameters of the guides, to be able to change the position of the guides and if possible also the rotation as in ikscape (accessed with a double click on the guide), place the gimp photo with the line distributes and that of the parameters of the inkscape guide!
