ST-JLance:That feature no longer exists. It has been replaced by the preview pane.
It would be nice to have the option to select which way to preview, either the classic 'floating preview' or the new preview pane, or both. Ideally, set like the skins - server default, domain may override, user may override.
Faster is relative. For example, we use Smartermail primarily as an internal product - latency and transfer rate are irrelevant because everyone is local. Browser render time is more issue, but as long as the message lists are 100msgs or less, it's not an issue. Server performance is no issue either: our 70-something users can't slam our hardware if they try. But those extra clicks add up to a lot of wasted time - it's not just a click. It's hundreds of clicks for every user every day (yes - prolific emailers).
