Handle tr checkpoints in a nicer way

[Sakrac]

tr just spams the console, could be organized much nicer & exported to .csv or something.

Created a separate window that shows trace listing, will leave for now. Should also add:

• Fake scroll bar
• Save result as .csv
• Clear results

Started fake scroll bar, works ok but not quite aligned with mouse
