Comment

this is similar issue to https://github.com/hluk/CopyQ/issues/1573 but the solution is to rewrite the command

i am not familiar enough with javascript or bash to rewrite the command, and also there is no example to get selected items to python

is it possible to add option to not remove selected item when command error ?
