#2 tracker field: allow url form udp / batch

[b0bcat]

1) In my experience the edit field for new or substitute tracker addresses

-- rejects trackers beginning udp:// which is a significant downside given the main public trackers are of that form not http://; and

-- rejects tracker urls fo the form e.g. <some-url>.com/hub.php

Is this hard-coded or can the program's behaviour be modified e.g. by use fo an .ini or like config file to allow without limitation any input for the tracker fields?

2) Less importantly but nice to have, can the program shell extension be made to allow selecting multiple .torrent files for batch processing in order either to add one or more specified trackers and/or to remove one or more specified trackers ?
