Very simply put, working with layers + Tilemap is a nightmare. As a very experienced artist, it is frustrating. Example: I’m making some grass, I copy something from Layer 4 to Tilemap 1… So I copy the 16x16 entire tile, hide layer 4 so i dont paste in wrong one, now only tilemap 1 is visible! The cell is highlighted.. CTRL+V… nothing. Oops, I need to swap layers! But why can’t aseprite do this automatically? This should be a feature.
Example logic: User has item copied, current layer is hidden, 1 other layer visible, and presses CTRL+V. Option checked for ‘Auto Swap to active layer: yes’. It will swap to the visible layer, and paste.
Another very irritating issue with layer swapping… sometimes, I copy something, and swap layers, and it incorrectly copies the entire layer! It will highlight the whole layer, and paste an entirely new layer. But I didn’t ask it to do that! I selected an object on the canvas, it auto-selects the whole layer in the layer pane without the user asking it to.
