Rated 3 out of 5 stars

I have mixed feelings so far, by ecample I have subscribed a feed which has about 50 items/articles today so far (and certainly yesterday at least so many, too) and I did not read one of them for the last 2 days but only 15 items from today (last 2 or 3 hours) are shown in Bamboo so does it clear or delete entries under certain conditions (more than x items, after closing Firefox or something like that) ? But that would be rather ridiculous, I expect that I can still read articles (shown in Bamboo) after 2 or 3 or even many more days if I do not mark them as read or delete them, of course

So what can be the reason for this ? I cannot find a recycle bin or trash in Bamboo so far so I cannot check if it deleted items or marked them as read so that they are away but I think that it does not show several items or just deletes them under certain conditions which is not very comfortable and not the way a feed reader should work

And how does one delete single items from the list after having read them (or not) ? Clicking on "Delete" deletes the whole feed so one has to resubscribe it, rather counterintuitive in my opinion
