In the popup panel that appears when clicking Add for effects, the sub-section headings such as "Sharpen" and "Color Adjustments" are very dark on the dark background.
They are hard to read at any monitor brightness level.
Is something not working like it should? Let us know.
I don't know if it's just me, but those look dimmer than usual. If you'd like us to take a closer look at this, do drop an email to firstname.lastname@example.org. Either way, I think those categories are probably something we could take a look at and find a better solution for!
