Sidebar Manager allows you to replace existing sidebars with creating a new custom sidebars, including very cool 
conditional logic. This way you can target any page, post or content with your sidebar. So for example

for blog, portfolio, and other content of your wish.
With custom sidebars manager you can also manage your widgets and set visibility to them (for example show 
your widget only at homepage)
