One thing that has always bugged me is how you cannot highlight a text and use the option to change colour for the entire highlighted text on mobile.

Other b tags work easily on mobile, you simply highlight the text and click on it to make it bold, include hyper links or any other features you'll like to add. But when you try to change colour on a mobile device, it doesn't work and the tags appear in front of the text rather than around it, probably due to the extra step of needing to select the colour but for some reason it works fine on desktop.

Let me know if this is something that can be fixed.
