default tab naming convention

[arbinish]

It appears that zellij's default convention of tab naming is to use some sort of an auto increment index. Is there a way to control this behavior?
here is a scenario:

1. I have 10 tabs open which has names like Tab #1 to Tab #10
2. Kill Tab #1
3. Create a new Tab. The tab name would be Tab #11. Can we not reuse the least available index i.e., Tab #1 in this case?
   I thought there might be some configuration parameter for this but couldn't find one in the docs.

My current hack is to have a zsh function which starts on every tab something like below:

set_tab_name() {
  # If zellij is not running this is a no-op
  if [[ -z ZELLIJ ]]; then
    return 0
  fi

  local tabName=""
  vared -p "What would you want to call this tab? - " -c tabName
  zellij action rename-tab $tabName
}

And invoke it at the end of ~/.zshrc. That said it being a feature would be a great addition..

Another option:

zellij_tab_name_update() {
    if [[ -n $ZELLIJ ]]; then
        local current_dir=$PWD
        if [[ $current_dir == $HOME ]]; then
            current_dir="~"
        else
            current_dir=${current_dir##*/}
        fi
        command nohup zellij action rename-tab $current_dir >/dev/null 2>&1
    fi
}

zellij_tab_name_update
chpwd_functions+=(zellij_tab_name_update)

Save this function in ~/.zshrc file.

If you are on fish shell:

function zellij_update_tabname
    if set -q ZELLIJ
        set current_dir $PWD
        if test $current_dir = $HOME
            set current_dir "~"
        else
            set current_dir (basename $current_dir)
        end
        nohup zellij action rename-tab $current_dir >/dev/null 2>&1
    end
end

# auto update tabe name on directory change
#
function __auto_zellij_update_tabname --on-variable PWD --description "Update zellij tab name on directory change"
    zellij_update_tabname
end

If you want to use git root directory

function _zellij_update_tabname
    if set -q ZELLIJ
        set current_dir $PWD
        if test $current_dir = $HOME
            set tab_name "~"
        else
            set tab_name (basename $current_dir)
        end

        if fish_git_prompt >/dev/null
            # we are in a git repo

            # if we are in a git superproject, use the superproject name
            # otherwise, use the toplevel repo name
            set git_root (git rev-parse --show-superproject-working-tree)
            if test -z $git_root
                set git_root (git rev-parse --show-toplevel)
            end

            #  if we are in a subdirectory of the git root, use the relative path
            if test (string lower "$git_root") != (string lower "$current_dir")
                set tab_name (basename $git_root)/(basename $current_dir)
            end
        end

        nohup zellij action rename-tab $tab_name >/dev/null 2>&1
    end
end

# auto update tab name on directory change
function __auto_zellij_update_tabname --on-variable PWD --description "Update zellij tab name on directory change"
    _zellij_update_tabname
end
