Sorry to bother you again~
I tried to open a gds file then hide all layers besides one layer we need, and the main window only show five objects.
When I select an area include these five objects, a running scroll at the right bottom of main window appeared and shows "selecting", even only five objects it spends a long long time.
Finally I found the element would effect the speed is edit=>select=>instances , if the option is checked, the program would check all the objects even these objects should not be visible because the layers are hide.
Is this situation correct or could be improved?
Another problem, is it possible to list the absolute coordinates/positions of selected text objects?
