I've some suggestions about the thread preview:
1) Add a link at the end of the preview like "Collapse this thread"
2) Add button "Reply", "Quote", "Mark as" near each post on preview mode
3) Automatically, collapse open thread preview clicking on other thead "preview"
Do you agree?

1 - Clicking on preview again collapses the thread.
2 - Agree.
3 - Disagree. I might want to preview more than one thread at a time. Especially helpful for identifying duplicate threads that need to be merged together.
