Hi, currently I can only enable onion skins on one layer. can you tell me how i can enable onion skins on all layers. thank you
Make sure you are up to date with Krita, in 4.3.0 all layers should appear in the Timeline docker and switching on onion skins on all of them should be easy (although you'd still need to click every one). Also for questions like that, about usage of Krita, please go to krita-artists.org instead. Here bugs.kde.org is a development-oriented website.
