- Set higher process priority for selected applications. (sets it to "above normal".)

- Support for multiple configuration files.

- Config creation through GUI.

OS support:

Tested on:

• Windows 10 22H2
• Windows 11 23H2 / 24H2
• Fedora KDE Plasma Desktop 43

Notes:

• Windows:

  • Windows 10/11 LTSC.

    • Should work without issue, but not tested.

  • Windows 7/8

    • Most features may work as the basic Windows API functions used should be the same.
    • Not tested on Windows 7 or 8

• Linux:

  • Should work on any recent distro using KDE 6 Plasma.

  • KDE 5 should work as well, but a few dependencies may have to be resolved.

    • KDE 5 is not tested.
    • KDE 5 support may break if kdotool is updated as recent versions have removed support.
    • qdbus calls might have to be changed to be KDE 5 compatible.

  • Window detection and management (essential) is dependent on:

    • kdotool v2.2+ (included in src/bin)
    • qdbus-qt6 calls

  • Screenshots (optional) are dependent on:

    • spectacle

How to use:

Create config

1. Click the "Create config" button while your applications are running
2. Select the application windows you would like to manage in the list and click "Confirm selection"
3. The application order is based on the current left to right positions. Click the arrows to swap places.
4. Choose the settings you want, type a config name and click "Save config"
   • Choosing an existing file name will overwrite the previous config

• Auto align

  • Click "Auto align" to go through the predefined layouts for the number of windows selected.
  • Custom presets can be configured in settings.json

• Update drawing

  • Will update the screen layout drawing with the current settings

• Restrict to upper half / restrict to lower half

  • For use with multi-monitor or very large screens. Useful for 2 stacked ultrawide monitors.
  • Toggle these on or off to use one the upper or lower half of the screen for layout calculations.

Apply config

1. Select a configuration from the dropdown menu to preview its layout.
2. Click 'Apply config' to activate the window layout defined in the selected config file.
3. The button changes color and swaps to reset mode.

Reset config

• Resets currently loaded configuration.
• This button is only available when a config is loaded (the apply button changes mode).

Toggle AOT

• Change the state of windows managed by the currently applied config.

• Useful for temporary access to the start menu or taskbar if it is covered by an application/game.

• When active it will pause auto-reapply.

• Will also put the application window on top when clicked.

  • Mostly useful with the hotkey. Will also work when no config is applied or no AOT windows exist.

• Configurable hotkey in settings.json

• Default hotkey: alt + home

• NOTE: Hotkey is not available in Linux, only the button will work.

Delete config

1. Select the config from the dropdown
2. Click "Delete config"
3. Click "Yes" in the confirmation window

• You can also manually delete the files from the config folder

Edit settings

1. Click the "Edit Config" button
2. Change the settings as you would when creating a new config
3. Save the config

Compact mode

• Click the "Toggle compact" to switch between full and compact mode

Take config screenshots

• This button will take a screenshot of all detected windows from the currently selected configuration and use them for the GUI

Open image folder

• Opens the folder with the images and screenshots.

Predict config

• Clicking this will attempt to find the best matching config based on the existing open applications.
• Always-on-top windows in configs are given priority for the matching.

Filter configs

• Will filter the list to only show configs with an always-on-top application currently open.

Toggle images

• Switch between basic and screenshot layout

Snap application on open

• You can set the application to open snapped to either edge of the screen instead of centered.
• This can be used to avoid opening the application behind an always-on-top window.

Auto-reapply

• Setting this will automatically reapply the current window settings if a change is detected.
• Will also apply the settings to new windows that match as they appear.
• Useful for games that has a lobby and launches a new game window per match, for example League of Legends.

Configuration Files

The files can be found in the "configs" folder in the same folder as the executable.

Configuration Format (config_\<name\>.ini):

---

[Window Title]
apply_order = Titlebar,Pos,Size,Aot # Set the order for applying settings
ignore_list = name, name, name      # Windows to ignore, comma separated list
position = x,y                      # Window position
size = width,height                 # Window size
always_on_top = true/false          # Set always-on-top state
titlebar = true/false               # Enable to keep title bar, disable to remove titlebar
exe = filename                      # File name of the application executable

---

Example:

---

[DEFAULT]
apply_order = 
ignore_list = 

[Opera]
apply_order = 
ignore_list = 
position = 0,0
size = 1706,1394
always_on_top = false
titlebar = true
exe = opera.exe

[About Fishing]
apply_order = 
ignore_list = 
position = 1706,0
size = 2560,1440
always_on_top = true
titlebar = false
exe = about fishing.exe

[Discord]
apply_order = 
ignore_list = 
position = 4266,0
size = 853,1394
always_on_top = false
titlebar = true
exe = discord.exe

---

Notes:

• Window titles in config are matched partially and case-insensitively against open windows.
• If the exe file name is included it must also match to apply the config.

Multi-monitor use

This application is made with ultrawide monitors in mind (32:9 / 21:9) and will work best on a single monitor or equal stacked monitors.

It should work with any rectangular setup of equal resolution monitors, although the default alignement calculations may not be as suitable.
