It has always been a problem of editing html for posting to html blog, then I found one editor which I can easiey integrate with this blog.
I learnt this editor from App Engine Site Creator. It uses this editor. I though I should be able to do the same since it is running on Python.
Just a few hours later, I am happying blogging with this editor. It has cutdown the time of composing the blog by at least half.
If you are interested, please feel free to grab the code from Github .
