I'm wondering how hard it would be to write a component that would
allow us to insert HTML on the sidebars (left or right). It
could be useful for posting site news messages or widgets. Would it be
too difficult to do something like that?
Using this component you'll get idea about:
- How to add new action
- How to create component settings page
- How to add content on right sidebar of newsfeed page.
V 4.2 comes with a WYSIWYG editor now to allow more comfortable editing.
