New version up (1.3):
Fixed some issues with sending the wrong parametres
Added support for ignoring libram changes when holy shield is active
Cleaned the code
The previous version isn't working properly and should be replaced if you downloaded it already.
I've tested the latest version a bit. The Holy Shield toggle is working perfectly. The Switching Between Mending/Truth is working fine, however The BOL checking seems broken as it never switches the libram of souls redeemed in, I've tried it with every combination of flags I can think of.
