Customize Existing WP Shortcodes Plugin - repost

Hello Freelancers! I would like to customize a part of an existing Wordpress shortcode plugin called Vision that I purchased over here: [login to view URL] The appearance of the current tabs produced by the plugin --> Refer to attached SCREENSHOT 1 a) Customize the look of the tab to look like this [login to view URL] -> Refer to attached SCREENSHOT 2 - Selected tab highlighted and bigger than the rest - Use the same clear and legible large font b) Have a plugin settings page for Vision plugin with settings to control site-wide color of the content boxes. Currently, you would have to use a slightly different short code for a content box of a different color. Because I have lots of posts containing these content boxes, it becomes cumbersome and I would like to have the ability to change the colors of these content boxes in one fell swoop simply by specifying it inside the plugin settings page by specifying the hex color code. The short code used within the post content to generate the content box would then be a generic short code and not one that is linked to a specific color. Currently the short code looks like this: [vision_content_box style="black" title="Awesome Content Box Title"] ...content goes here... [/vision_content_box] The ideal generic short code should look like this, with the style removed: [vision_content_box title="Awesome Content Box Title"] ...content goes here... [/vision_content_box] Thanks for reading my project brief and let me know if you're up to it! Cheers!
