i tried leonardo demo version

not impressed to be honest,

1º i can't do backtesting in the demo version with macd, can i ?
2º there is no 2H in the time step of the graph
3º the design looked so nice in picture then after use it, everything is so confusing, such high lack of deph in windows and buttons, its like too flat, no colors, no nothing...

what programing lang was used to make leonardo? looks so out of standards, also did not run in windows xp.
