I think the ability to pin a colour palette to a particular writing tool is necessary. Every time I want to use a new tool, I have to pick the colour palette I want for it. For instance if I want to pin the highlighter colour palette to the highlighter tool, and a muted colour palette for one technical pen, and brighter colour palette to another technical pen and ballpoint palette to ballpoint. I should not have to pick and change the palette everytime. Right now, every time I switch from one pinned tool to another, I have to select the colour palette I want. Just like he ability to pin tools, there should be the ability to pin a palette to a tool of choice.
