Spent a day on the enhancement of my rich media map, first version has come out.
1. move import buttons, add image, text, video into pop up panel.
when user click plus button, an additional panel will gracely move from right to left
2. move edit, delete, rearrange button into top operation panel.
3. add color picker to select push pin color
4. add confirmation panel when user click delete item
5. disable text scroll, so the entire length of document will equal to the height of text element
