Hi I'm new here, and also fairly new to Krita. I have version 2.9.10 downloaded on my desktop and my laptop and am going through Scott Petrovic's excellent book and I'm trying to learn how layers work. When I try and use Layer Styles from the top drop down menu the middle panel isn't activated - it says "Blending Options (Not Implemented Yet)". It works properly on my laptop although I only use it for emergencies because I find it easier to see with my PC's big screen. I'm sure I've pressed something I shouldn't have and googling all over the place hasn't found me a solution. Any help will be much appreciated.

No, that's right, blending modes isn't actually implemented yet, so it's not your fault. It's an incomplete feature
