Too difficult to discover the meaning of ⓘ in colour settings
In colour settings it's too difficult to discover that ⓘ means "Full-screen display correction not possible with this profile".
Assuming the user even notices the ⓘ icon, clicking on it does nothing and as they keep moving the cursor it never hovers long enough to show the message that it should. I thought colour profile support was broken for the past couple of years till I realised this.
