Is there a way to make the chart tab bar multiple lines?
- Scrolling Multiple Charts
- Show All Chart Tabs
- Scrolling multiple charts together
There is already a lot: https://www.mql5.com/en/search#!keyword=multi%20symbol
Do you know this in the terminal:

I want to change the chart tab bar so it doesn't use the side scrolling instead shows all the pairs on multiple lines.
Unfortunately it's not possible.
You can use ALT+W,M to display this Window allowing you to choose your chart.

So stop using it. Just control+tab (or shift+control+tab) to go to the next chart.
