Groups
As your subscriptions list grows, it becomes harder to manage them. endo not only facilitates grouping subscriptions, it also lets you make smart groups using rules that can be as simple or as complicated as you want. You can quickly navigate between groups using the groups bar or configurable keyboard shortcuts. You can rearrange groups and you can drag subscriptions around as well.

Customizable
Tastes differ, so endo allows you to see the groups and articles the way you prefer it. As a flat list or hierarchically, with summaries or without, with tags or without, groups as icons or as text. Your mileage may vary. To navigate between groups and articles you don't even need to touch your mouse once.

Spotlight
Want to quickly find an article? Use the quick filter in the article list or use Spotlight. You can search using Spotlight using the Finder or from within endo. Metadata stored in Spotlight for endo articles include keywords (tags), authors, and URL. Information wants to be found.

Flagging, Blogging and Bookmarking
Articles that you have found to be of interest can either be flagged for permanent storage, send to your blog client (ecto, for example), or bookmarked on del.icio.us. endo's del.icio.us bookmarker supports extended descriptions, tags, and datestamps. It even creates a summary of the articles contents for you. Sharing your interest could not be easier.

Plugins
The power and flexibility of endo can be extended using plugins. Plugins can do as little as creating a subscription or as much as providing the actual feed. endo comes with four built-in plugins. There are plugins to create del.icio.us, Flickr, and Technorati subscriptions. There is also a plugin that can run your own scripts. These scripts can be in AppleScript, Bash, Perl, PHP, Python, or Ruby, and should generate feeds.
