[Feature] Change progress bar color

[szajni]

Hey there, would it be possible to add an option to change the progress bar color? Its yellow by default, and i'd love to customize it to my needs, and i couldn't find any option to change color of it. Thanks.

This should include the background of the bar not just the yellow part if that wasn't obvious

And other suggestions that might be cool to have

Border customization on the achievement for the outside border and add borders for the image and progress bar

And Rounding support for the image and progress bar
