I'd love to see the import as paused for arbitrary files.
Same here. With the addition of the "Unimportant files in PAR2 set" listbox I kind of expected there to also be a listbox of custom file masks to import as paused (Setup->NZB #2). And a listbox for "Delete after successful unrar".
I've set up a script that deletes the unnecessary files but why even download them if I'm never going to use them...
Some collections have sample files without the word sample in them. They are usually at the bottom of the queue and therefore are downloaded while and after the collection is extracted. So the cleanup script will be useless unless I add a long enough timer (with the choice command for example). Either way those files are using resources for no good reason.
About minimizing the script window... The switch /MIN belongs to the start command. But since you can't run start as an application you will need to call it using cmd.exe. At the end of the batch script you may need an exit command to close the window.
cmd.exe /C start "Cleanup" /D "C:\Program Files\AltBinz" /MIN cleanup.bat "$d" "$u"
That will still steel focus from a full screen application so the shortcut method suggested by Hecks is a much better solution.
