It puzzles me that I can see drawings done on a 2 hour chart are visible when I switch to another timeframe, but are not visible when I have open 2 or more windows of the same instrument. Please make all drawings show up on all timeframes of one and the same instrument in all windows.

The chart-synchronizer-plugin-2 works sometimes, sometimes it doesn't. If it does, then it only synchronizes vertical lines, but not price markers. It is a mystery to me why this tool is restricted to vertical lines; either way, I hope it is technically possible to make all drawings appear on all timeframes.
