I can't understand others, but we should delete segment of a track. Press `SHIFT` key, at the same time double click the segment which you want to delete.

If you select multiple tracks or text items using ctrl+left-click and then go to move them all at the same time it selects the one you use to grip a hold of, and only moves that one instead of all of them. For the welding one, if you draw a square (or a hexagon, or other unfilled shape), you will get a line with corners along it's length that winds up at the same place as it started. There are 2 issues with this. a) you cannot grab the whole shape (line) and move it, you have to move each corner independently, leading to inaccuracies. It makes irregular shapes and unfilled shapes on the document/silk layers difficult to manipulate. b) the point where you started and stopped the line (which will be the same place in the case of an enclosed shape) will be 2 points and thus that corner will need to be shifted twice. These could be welded together to form a single continuous line or an enclosed shape instead of being a line that starts and stops at the same place. If want to merge 2 existing tracks/lines together into one you cannot currently, you must delete one and re-draw it. Hope this helps with understanding the request. Braedon

Got it, Maybe you can use `arrow key` to move the selected items now. will make the movement better later. Yes, now we can't merge them at present. Add your request to todo list ( a long todo list) Thanks
