Hello,

The codeless sliders are arranged based on their creations time. To reorder them after you have already created them, it’s not possible using theme options. But it’s totally possible with the help of “Post Types Order” plugin.
Find the plugin here. It is very compatible with theme.
After installing, a “Re-Order” option will be added to the Codeless Slider options (screenshot). Drag and drop slides to reorder them.

-You can add a button to header. Set the instagram link to it. To add this go to your Header Options > Add Button to Header, set it ON. Then set up the name of the button and add a link to it. See screenshot. An example of it’s use is in this demo.

Note: I closed this other topic of yours “Tower codeless slider help” as a duplicate of this topic.
Please open one ticket per question only.

Thank you for your cooperation.

Best regards!

Hello,

The header style of the sliders should mach the header style of the page’s. I changed the header type to dark for all slides in Codeless Slider options > Layout > Menu & Slider Navigation Color (screenshot)
I added this css into your Custom Css Box:

.btn-bt.business { 
    padding: 12px 15px !important;
    margin-right: -32px !important;
}
header#header #navigation {
    float: left !important;
    margin-top: -47px !important;
}
.header_tools_divider #navigation {
    padding-right: 0px !important;
}

To fix the alignment of menu items. Their width exceeded the space left between logo and instagram button, so the menu shifted down.
This is the result look now: https://postimg.org/image/3c7hpsd56z/
