I have - and always have had - the option to 'Allow multiple files on the command line'. I have however noticed a difference in behaviour when selecting 'Edit' versus selecting 'Send to TextPad 8', in that the former loads each file into a separate instance of TP whereas the latter performs as I expect, i.e. opening each file in a separate tab in a single TP instance.
I have done the usual dance of resetting the configuration, closing then reopening TP, even doing this between uninstalling and reinstalling TP, to no avail.
