Mercury Editor

Mercury Editor is in the field of web editing, but acts as one of the best tool in transforming the nature of a company's web site. Secondly, Mercury Editor permits HTML inputs, which allows inclusion of content from different locations. Again, to customize the look of your site, Mercury Editor allows the aspect of dragging and dropping of items.

One can edit the content on the user interface itself this makes this editor very unique. Maintained by community via GitHub and open source is another good thing

Its really easy to install and has a bunch of configuration options. Overall it works pretty much at face value, its a wsywig editor without a ton of headache..
