A new version of the All Read plugin for Omea Reader/Pro is now available.
All Read is a tiny plugin that adds one button 
to the main Omea toolbar that lets you mark all displayed messages as Read. You can use this button instead of the context menu or keyboard shortcut.
Version 1.1 is a minor release that adds the following features:
- you can now use the All Read button with views, feed folders and web bookmarks;
- All Read now works properly with Omea's Newspaper View.
Here's the download link.
My thanks to monkeyking for suggesting these updates.
