[moveColumn] threshold option

Could we add a moving column threshold option so that column moving does not start until the threshold is met?

Short description of our case: Because the column menu button is quite small for using with a tablet or mobile device, we decided that we want to add a custom header template that makes the whole header act as a button for the menu. This causes problems while trying to access the menu because not every mouse click is perfectly still, sometimes the user triggers a move action on that. Therefore we thought that adding a threshold option for when moving a column should start could fix this.

Are there any alternative solutions for this?
