Hello!
Sometimes the code, or HTML page gets many children and it becomes hard to scroll through it, or to write an additional code, since a large part of the view contains tabs or spaces for indentation.
I would like to suggest an additional feature, a user-definable parameter that will allow an automatic horizontal scrolling for ST3 based on the position of the leftmost symbol that is not a space or a tab in the current view.
So, ST3 would automatically scroll the view horizontally for the amount of number of spaces/tabs that are included at the beginning of all rows that are currently in the view.
