This is a good feature request, +1

This is the only thing I don't like about ctrader, so much so that I use tradingview.com for my analysis then switch over to ctrader to enter and manage trades. The inability to scroll in/out and move charts around by holding down the mouse, custom bar sizes etc. It's annoying so as a result i only use ctrader to enter trades.

I agree with this. Adjustable font sizes are a must both on the vertical scale and also the order entry lines, for example if i have a buy stop order in its very difficult to read the pips, profit numbers etc.
