Long time user, not so many posts'er.
I've never been a fan of how you choose colors for Fences. It would be so much nicer to have a few different things.
1. A standard... typical color picker window like nearly every other app that exists on windows. You know, with the window popup, RGB, HEX, and HSV controls, and a color box or wheel.
Really the big problem I have with the color choosing is it's just sliders. It seems this is really Hue / Sat already. But it's very difficult to get exact colors for same fences when you want maybe just to two or three of the same color value for example. But also there are palettes out there that I like to follow and use.
2. Also would be great to have at least a single palette to save to. Bonus points for more than one palette to save to.
Oddly enough you guys have a palette window for the label text color.
Cheers and hope I can see these features one day. Still love fences though and always refer friends to it with billions of icons on their desktops haha.
