Sorry for bothering but is it possible to select and copy pixel art in a tab then go to a different tab and then paste it there? or is has not been implemented yet, again very sorry for bothering you. Also how do you delete the guide marks/lines?
Nothing to be sorry for! And yes, you can use the rectangle selection, copy the selection with Ctrl-C, go to the new tab, make a new selection and press Ctrl-V. We will work on improving the selection system for a future update, but this feature will not go away.
