Pivot Points, sharing trendlines and window size

I have three question:

1) how can i put in the intraday pivot points? I have tried the pivot studies but that doesn't show the S1/S2/R1/R2 and P levels.

2) when i have four charts of one instrument over different time periods, and I draw a trendline, on lets say the 15min chart, the trendline doesnt get shared on the other 3 timeframes. How can I see the trendline on the other charts also?

3) it seems the window focus is locked. So when price go below or above the Y-legend i have to resize the window. How can I make that auto-size?

right click on the price scale... select reset.
