While there is a quick reply button I don't usually use it if I'm responding to a post, such as I'm doing with yours. However, the only two options shown at the bottom of this post are 'post quick reply' and 'go advanced'. In order to get to preview post in a regular reply (vs quoting someone) I then have to click on go advanced & then preview post. Not everyone knows to do that & I just (personally) find it easier to copy what I've written vs. doing multiple refreshes, which are more clicks.

It would be easier if IB lengthened the time before they basically kick you out/think you're not active, but I realize that's way-y-y down the priority list.

Cheers.
