MediaPress not functional, and some needed Improvements

Hello Sir,
I installed MediaPress. And when I click on any of the icons, nothing happens. See it here– https://prntscr.com/1oxnzoz

It doesn’t open any window for me to select media to upload. How do I fix this?

2.) I selected Photo,Video, Audio and Documents. But from the screenshot above, you can see that documents Icon did not appear.

How do I fix this?

3.) The MediaPress icons are outside the Wall. This looks like bad placement. They should be under the wall, so that they look handy as you are typing content, and can easily see them close by.

As an Example, I have activity Plus Reloaded plugin installed on the website. You can see the comparison I made between the placement of Activity Plus Reloaded plugin and MediaPress. You can see where Activity Plus Reloaded plugin sits, and see where MediaPress sits from here– https://prntscr.com/1oyfb5r

MediaPress doeasn’t sit properly in the Wall. How can we correct this?

4) MediaPress Icons are bland and not too beautiful. Can you add option for us to add background colour to each Icon? Meaning that we can choose background individually for Photo, Video, Audio, Document, to have something that looks exactly like this– https://prntscr.com/1oyoog9

And can you also make it possible to choose “Icon Display Style” like Icon only, Square, Border Radius and Circle?

Here is a sample of what I mean– https://prntscr.com/1oz1ho7

Needing to hear from you soon/
