Having to align pads by mouse or by inputting x/y values for each pad is not very productive.
I should be able to place a single pad, then select a tool and input number of rows and columns of pads and horizonal and vertical pitch and have the pads copied, placed and auto-numbered.
Pitch should support negative pitch to have the pads create above or to the left instead of below and to the right.
FYI this is the script I use. I still think this would be a useful built-in tool to create PCB libs.
Select the first pad, numbered 0, then run the script to create the given number of rows/colums, works well for grids/SIP/DIP but not for QFP.
// SET THESE (units are canvas units)
var columns = 8;
var rows = 8;
var hpitch = 16;
var vpitch = 16;
// LEAVE THIS
var count = 1;
var selected = api('getSelectedIds');
var newObjs = [selected];
for(var h=1; h
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
In this case, if you can use https://easyeda.com/Doc/Tutorial/API.htm#EasyEDAAPIPlug, you will find it is easy.
You can use script to create pads.
