Custom Blogger Editor UI With Stylebot Chrome Extension

Several users were getting annoyed with Blogger post editor UI which, when larger image displayed, the horendous horizonal scroll takes effect. When this happen, the texts in a paragraph will also flow outwards beyond the editor width, making it (a bit) harder to proof read & re-inspect the contents. User's usually experience these issues on desktop with a wide/large screen monitor. The Blogger post editor display a small 700px in width,  with some greyed out empty space to the left & right. Why not make use of these empty spaces...
