Being able to set the target of links within a post--whether the link opens in a new tab, window, or the same tab/window.
At the moment all links seem to default to opening in a new tab.
If the link is referencing a post within the same discussion, it should automatically open within the same tab/window.
This works now with direct reply links, but not with markdown links.
The other potential feature I wanted to bring up is an option to print discussions.
Some way to lay out an entire discussion (or otherwise split it up into pages) in a simple rich text format that's easy to copy, download, and print.
