BUGS of default settings for the drawings in the chart - beyond the strength of cTrader developers

1. It is VERY FRUSTRATED that simple option with check box in DEFINING THE DEFAULT SETTINGS FOR DRAWINGS IN THE CHARTS - DOES NOT WORK!

I think that cTrader developers are doing sophisticated things... but are not able to manage simple once. Its really frustrating that simple option does not work.

2. The same is with simple functionality I have mentioned - ICON FOR TEMPORARY HIDING ALL INDICATORS or icons for every indicator to hide it if not necessary for the moment.

3. I am not even mentioning about functionality from Trading View - SYNCHRONIZED CROSS HAIR CURSOR ON THE CHARTS.
Probably it is agreement with third party company to provide this functionality for extra money we need to pay - what is present today.
 

This simple things are probably beyond the strength of cTrader developers.
cTrader developers are doing everything to make less people use cTrader platform. Its good direction to make cTrader useless...
