Thanks Shaon for this useful plugin, it's indeed the best existed front posting plugin!
I have small suggestions:
1- After submitting a new post, it would be nice to go directly to the new added post page other than returning to the posts page.
2- It would be better to make category as drop-down list other than check boxes (when there are too many categories, it would take too much space in this case).
3- Adding "Tags" field to the add new post page.
4- Adding "Date" to the posts' table with the ability of sorting depending on it.
5- Adding "Edit" action beside "Delete" and clicking on the post title in this case would take to the post page (since for now there's no way on the posts page to go to the post's page).
Thanks again for this lovely plugin.
