Been trying this browser out for a little while now, and like what I've seen so far. Is stable and fast, and renders pages well.
The built-in ad and pop-ip blockers work. Don't know if this is related or not, but those pesky "I like/we recommend" windows in the LRHC of a page on some sites is also minimized; for this alone I like this browser.
The backwards/forwards functionality is also quite quick, along with extra little icon/buttons for a dropdown menu of past URLs to choose from.
That said, there are several improvements that come to me straight away:
1) As is, when this app is open and I open a .txt file (by double clicking it), it opens it within the browser, even though my default application for .txt files is still TextEdit; by using the contextual menu I can still open the file in TextEdit. Looking in SB's preferences I can find no pertinent fields to chage, nor does there appear to be a thread on the SB forum about this.
It's nice having this feature, i.e. viewing .txt within the browser, but it seems how it functions could be tweeked and preferences provided for.
2) The download manager window is a bit minimalistic; it could use more info, such as the file size and amount downloaded so far, as well as time remaining
3) It would be nice to have an auto-update/install feature. As is, if you check, it just directs you to the SB download page and you have to do everything manually.
4) This is more an issue of the SB/Flashpeak website: the versions page refers to ver 4.x, while the newest for Mac is 1.x; I'm guessing the higher-numbered versions is for Windows, but in any case it is confusing/inscrutable.
