I use this and I experiened like this:
So I have to change this line in `~/.p10k.zs` The line is AROUND at line 400 :
from: (( $#branch > 32 )) && branch[13,-13]="…" # <-- this line
to: (( $#branch > 40 )) && branch[20,-20]="…" # <-- this line
.
It the branch name is over 40 char, It wil be cut from the 20th chat til the last 20 char.
