frontrunner tool suggestions:

• refresh button
  it seems closing the box and reopening it is the best way to use this. A refresh button with maybe some small rate-limiter would improve functionality and prevent a spam of refreshing from bot/macro.
• post time/age
  I just noticed one that said something like 200% ROI so I jumped on it without thinking twice, but inspecting the post to find it had an age of 1-minute tells a different story, the actual reward is something like 3~5% because of the reverse auction mechanic, and with small changes coming to that mechanic in HF20 the best way for the tool to fit any change might be to simply show the post age and let the user decide.

anyway, it's an awesome addition, great job ^_^
