no. in my version i have separate tool for lines... and it doesnt contain darkening/lightening...
and as i said - also managing selection more than only copy/cut/paste/delete :/ (read - darken, lighten, fill all, draw square and circle)
You found how to draw lines (with the Shading tool) right?
if you need any help, feel free to ask in Pixelorama's official Discord Server
