Favorites time frames

There are too many time frames selections to traders like me, I would like to be able to select from the all the time frames only 2-3 to be shown and to be able to add or delete time frames for your personalisez time frames selection.

The list is to long, it takes 3 secods to change time frame from 1m to 1M with a low sensitivity laptop touchpad and some times when I am in hurry,I go a little aside from the list with the mouse and the list dissapears, I have to go up and open again.
