For now, I want to keep the amount of blend modes added to a minimum. I don’t want to overflow already packed menu :< It’s not a perfect solution, but it’s temporary before we split Alpha and Color blending modes into two dropdowns.
Sadly, I don’t have currently enough spare time to finish both this patch and splitting blend modes selection before next release. I barely have time for this patch 
The variations listed were chosen because those actually can be used to simulate traditional paints. I know that there are other commonly useful modes like Overlay, Color Dodge, Screen and such, but I want to cut the list short for now
You can write modes that you would like to see kept, maybe I will add more and I can take suggestions into consideration.

This mock-up is terrible, and I didn’t explain it properly, sorry for the confusion.
First drop-down is Alpha (A) blending modes, they only specify how Alpha channel is blended, those would be for example:
- Over (it’s a current way of blending alpha for most of the blending modes)
- Erase
- Wet
- Wet-smooth
- Wet-smooth Lite
- Wet-dry
- Wet-dry Lite
- Alpha Darken
- Other or future Alpha blending
The second drop-down is Color (RGB, HSX), those are modes that describe how color channels are blended:
- Normal
- Add
- Multiply
- Overlay
- Color
- Hue
- and a “hundred” more xD
Then you can make any combo you need. For example, if you want current blending modes behavior you use Over + any available for Over color blend mode, like:
- Over + Normal = Current Normal
- Over + Multiply = Current Multiply
- Over + Overlay = Current Overlay
Wet modes would be:
- Wet + Normal = Wet Normal
- Wet + Multiply = Wet Multiply
- Wet + Hue = Wet Hue
- Wet-smooth Lite + Add = Wet-smooth Lite Add
Erase would be an exception that when active disables color blending modes.

Thank you, I have to think about users that already complain about super packed menu, that’s why I decided to minimize amount of new blend modes before it can be implemented nicely.
