thanks for your prompt response

I figured bookmarks could be used to that end, but they also cause a separate page to be loaded. and that's fine. the problem IMHO is that there's not an option to open that page on another tab, rather than replace the current one. don't get me wrong, I don't want JavaScript, that's one of the reasons I'm in love with snac. but I know it's possible to send actions to the server by opening links on another tab. I don't know why the action buttons in snac don't work that way. maybe it's a GET/POST thing?

I'm glad we're on the same page WRT wanting/needing the "already seen" marker.

is this a good place to discuss future features? or is there a mailing list or somesuch? I generally like to get agreement on feature designs before setting out to implement them, and I've historically participated in projects that used mailing lists quite heavily, even for patches.
