Mark a floating window as "Pinned" that follows me between workspaces

[webdz9r]

As a user .... At times (try not to) I have to multi task and switch workspaces. It would be great if I can mark a floating window as pinned (IE: terminal windows with process running) this would mean the pinned floating window will follow me as I navigate between workspaces.

Reason:
This would allow me to keep the window open and floating regardless of the workspace I change so I can monitor my window progress.

My workaround for this was the following, I set in the config:

exec-on-workspace-change = [
    '/bin/bash', '-c',                                                                                                                              
    '~/.config/aerospace/on-workspace-change.sh $AEROSPACE_PREV_WORKSPACE $AEROSPACE_FOCUSED_WORKSPACE'                                                                     
]       

and then I have a script ~/.config/aerospace/on-workspace-change.sh which has:

#!/usr/bin/env bash

# Define pinned windows with app-bundle-id:window-title-regex-pattern format
PINNED_WINDOWS=("com.microsoft.Outlook:^.+ Reminder")

AEROSPACE_PREV_WORKSPACE=$1
AEROSPACE_FOCUSED_WORKSPACE=$2

# Function to check if a window matches any pinned window criteria
function is_pinned_window() {
    local app_id=$1
    local window_title=$2
    for entry in "${PINNED_WINDOWS[@]}"; do
        IFS=':' read -r pinned_app_id pinned_pattern <<< "$entry"
        if [[ "$app_id" == "$pinned_app_id" ]] && echo "$window_title" | grep -E -q "$pinned_pattern"; then
            return 0
        fi
    done
    return 1
}

# Function to move pinned windows to the focused workspace
function move_pinned_windows_to_focused_workspace() {
    aerospace list-windows --all --format '%{window-id} %{app-bundle-id} %{window-title}' | while IFS=' ' read -r window_id app_id window_title; do
        if is_pinned_window "$app_id" "$window_title"; then
            aerospace move-node-to-workspace --window-id $window_id $AEROSPACE_FOCUSED_WORKSPACE
        fi
    done
}

# Main logic to handle workspace change
move_pinned_windows_to_focused_workspace

@nikitabobko obviously this a rather slow implementation, e.g. takes around 200ms due to all the process instantiation and their processing. It would be ideal if a command to pin a window could be introduced and on-window-detected and hotkeys could be used to call that command.
