Please add a little bit of customization for the worksheets. Right now, the title of the worksheet is automatically set to Accent Color with no way to change it. My accent color is not a good color for a title, but the only way I can change it is to change my global colors and therefore also change the accent color throughout everything.
Please make the title color the same as the titles elsewhere OR even better make it customizable.
Also, the card image that you set in the settings is only for internal purposes. Why? That would be a perfect way to add a custom designed header to the worksheet.
These 2 minor changes would make the worksheets look a lot better.
