If i'm doing ls /var/<tab> there's a bell icon showing on the tab bar. Please let me disable the showing of the bell icon on the tab bar, it is something unexpected moving in the corner of my view area, thus catches my attenntion, makes my eyes focus there, losing my focus and my general productitivy.
On the other hand, if i want ls/cd not to produce a bell, i can configure them not to actually produce a bell, so i guess that's the real fix.
