[Feature request] Day of the week header in the calendar dialog

Hi cTrader Support Team,

I would like to suggest a nice-to-have feature for the calendar dialog in backtesting and optimization. I think there should a header row here (highlighted in red) to indicate the day of the week (i.e. M T W T F S S). It would be handy to know what day it is instead of having to figure it out mentally every time we open the calendar.

Kind regards,

Tuan Nguyen
