Pencil button suffers from low contrast

I only discovered this button because I stumbled across your blog post.

Using light grey on a white background isn't ideal. The icon itself isn't much help either. It's a pencil next to a text box, which doesn't really convey the idea of "click here to draw polygons".

I'd suggest using more distinctive icons like geojson.io:

The problem is that it is a disabled button and should not be that bold.

Another problem might be that this button is invisible if the custom model is not enabled and so this is a bit hidden. But this makes sense from a functional perspective. Not sure how to improve it because clicking on it and enabling the custom model might be counter-intuitive (?)

I'm unsure why the icons you refer are better in this regard. The current icon could be also interpreted as a pencil next to a rectangle.

I would say that other elements also suffer from this problem, but to a lesser extent.

• gear icon
• add location
• Options

Maybe you could find a different mechanic to mark enabled elements instead of using grey for disabled ones. You're already using a blue shade to highlight the active profile. Maybe you could alternate between black and a blue?

Changing the background color might also be a valid approach to increase contrast.

Note that I have good eyesight, so this is a minor inconvenience for me. However, visually impaired users may not be able to fully use the interface.

I wouldn't change that to be honest.

The current icon is the widely used for text editors and text input boxes:

That's why i would rather use something like this instead:
