Universal Bottom Bar

After my first blog I wonder on which topic should i write next blog.
Final i find the topic.
While doing programming i used drawer and bottom bar both then i decided to combine both and i come up with new bottom bar.

It is less complex compare to another bottom bar. I know it has less functionality but this is just a begging and i will going to make it as a library.

Here is the Universal Bottom Bar
