Hi pitiwazou! Great addon, still learning it.
My problem is, that I don’t seem to have the Modifier listing on left.
I fetched recent speedflow_2_80_v_0_0_18 from Gumroad and today’s Blender 2.80 Beta from blender.org. I also resetted to factory settings before installing Speedflow. Still no Object modifier listing on left. Do I need to enable it somehow? All other functions seems to work.
