Good one.

We now use more of a mix. I think I like the idea of naming the icons what is is presenting, we already do for a lot of icons, instead of naming it to the function or purpose of the icon.

[ghost]

that means we'll have to rename a lot of icons (e.g. settings, edit)

@delnyn sort of true. This solution can have a big impact

[ghost]

or we can just write a naming convention without changing the name of the existing icons
