To expand upon a suggestion made in an earlier thread by Kyle (topic 3768), I think removing the text
"You attempt to pick the [NPC]'s pocket..."
and
"You succesfully pick the [NPC]'s pocket..."***
from the game chat when it is set to "Filter" would be a good quality of life update for thieving training. (example below)
*** I also think that this could be an opportunity to correct the spelling of "succesfully" to "successfully", can never have too much polish
