Thank you for quick response
The main reasons are that we have to import a lot of posts from the current blog and make it easy for the users to create blog post. We want to show all blog posts in the portfolio grid (we are not going to use the project). I also want to use advanced custom fields, disqus and other plugins on the post. In another page we want to order by posts by categories on another page and use plugins to get most popular posts.
I custom template would be great. Thank you. Do you need more information?
