You can ask me
The options are going to change a bit, as some of them only make sense for the beta. But here's a quick rundown:
1) Servers manager. This is where you specify userid & password, etc. This will be simplified (the ability to set the server host & port will be removed, as will the ability to sync to multiple servers -- that's useful only for the beta).
2) Synchronization. Some interesting things here. Obviously you can set how often you want automatic syncs to occur, but we're going to expand this to let you set a schedule. You can also turn on what we call "smart synchronization", which basically over time determines what your reading habits are and schedules syncs accordingly. The page optimization option lets you do some post-processing on the pages to account for some BlackBerry rendering oddities -- it's slow right now, we're working to speed it up. The connection type will probably disappear, as socket support is very uneven across carriers. The transport type determines how the device connects to the sync server -- in the next version the best transport will be determined automatically.
3) Browser properties. This is very similar to the options you see on the BlackBerry's own browser.
4) Forms manager. When you fill out a form, the form stays queued until you do a sync, although the next version will optionally let you submit the form immediately. This section lets you track those submissions.
5) Online requests manager. Sometimes when using AvantGo you'll come across a "page not found" error. This usually happens because (a) the channel refers to an external page or (b) we had to flush some pages out of memory on the system's request. When you come across a missing page you can do what's called an "online request" to fetch it right away. This manager lets you see the states of those requests. We may remove it, it's not clear how useful it is.
6) Channels. This shows you the channels list. There are some inactive channels in the current beta that shouldn't be there, BTW.
Actually, the channels list reminds me. If you're in AvantGo and you want to quickly jump to a different channel and see which channels have updated themselves since you last read them, press the ALT key and then scroll up or down.
We'd love to get feedback from users on what they like or dislike about AvantGo for the BlackBerry, although I'd ask you to hold off on the comments for a day or two and the new beta client is out for testing.
