PalmX keeps stable information pages separate from the chronological feed. About, installation, design notes, and changelog content belongs to Pages; short-lived conversation belongs to Posts.
The top navigation exposes both kinds of content without collapsing them into one stream.
A native WordPress comment can bring this thread back to the top without changing the original post date. @horse this is the activity-time example.
The nested reply stays in WordPress comment_parent, so the thread remains native while the activity time updates.
