It would be a real boost in UI to have an unread items counter near each category name (even the custom ones) + a small color/highlight customization panel to set the border of the unread items after each user preferences (or something similar on this idea).

keyboard shortcuts ala Google Reader?

I don't see the point of an RSS feed it if doesn't let you see the entire content of a post, including text, photos, and videos like Google Reader. It would make the site much more functional and a competitive replacement for Reader.

I would like to read news in bed on a dark background.
A good example is the Pulse news reader for the iPad by Alphonso Labs.

Like on google reader, a category that would show all the news from all other subjects

In google reader when you scroll away from an article, it is marked as read. I like this setting because I prefer to skim many (hundreds) of feeds and headlines and let the less interesting ones go by.

I just want to thank you for creating a real, viable alternative to Google Reader.

It would be nice to have some sort of highlight feature or weight feature that gives more visibility to most important feeds in a folder. Sometimes i have feeds with a few post per week but that are very important and others that i dont care much. So it would be nice to have different color, font, header or a bigger "div" for news coming from "prioritized" feeds (you can give weight on settings using "stars" or + / -)

If you follow a lot of news sources that have some overlap in the topics covered, it would be nice to get similar news items grouped together.

I want to be able to click on an "+" on the right and expand article on the same page. Not have a pop up on the same page or open a new page.

Its like the "group" functionality in Excel.. (...and don't kill this idea because of reference of a Microsoft product!)

Add an option dialog (or some other method of input) for font and font size selection. This option is mostly just for accessibility as it can irritable to strain your eyes all day.

There is a lot of news to go through. Can you add a 2 column block visual view?

One feature I enjoy about Google Reader is the ability to search past feed items from a long time ago, such that they might not still be in the actual rss feed. This makes it easy to share an article with a friend if it comes up in conversation a month later, or if I remember seeing a past article but can't remember where I saw it.

No yesterday news.

It'll be awesome to be able to track your personal reading statistics.
Which sources do I read the most and from which categories? How do these values change over time?....this kind of stuff.
Would be appreciated!

Using tweedeck too, their notification system is really cool.
To give the possibility to goodnoows user to manage their notifications for each topic would be awesome because currently if we wanna see what's new, we must go on GoodNoows.
We don't necessarily have the time to check. Notification would be desactivated.
