This app has a lot of potential but it's buggy. Some bugs are very obvious, bugs you shouldn't make if you have been writing software for a while. For example, if you have one or more bookmarks selected and you switch between tags for some reason it remembers the selection. It's a weird design choice because the articles will be completely different but lets give the developer the benefit of the doubt and let's say that it's intentional. The bug is that even though the selection remains where it was, the program's logic behaves as if those items were NOT selected: - you click them once, their selection doesn't clear, they stay selected until you click them twice. - you click somewhere else (without holding ⌘) and their selection doesn't clear. It's not a big deal but it took me less than five minutes to notice this bug and to know exactly what's causing it (data out of sync with view). That doesn't give me a lot of confidence in the product.
