Better resume trading support. As far as I can see, Zorro still doesn't exactly pick up trading where it stopped. When I restart and I click result, the chart only shows 1 day of history and the portfolio.txt doesn't show the actual portfolio, even when the strategy ran for weeks. I don't know if this is fixed already, but in former Zorro versions restarting Zorro also messed with the Z12 portfolio. Just after restarting, like 20% - 30% of all open trades were closed almost immediately.

And I want to report a bug (didn't find a better place for this): I'm using Windows 10 on a Core2Duo Notebook (slightly above 2GHz). When I hit start in Zorro (I only tested this with Z12), Desktop Window Manager jumps from 8% CPU to 55% - 58%, causing the fan to run at all times.
