Floating Tiles: no-stacking stacking window management for KWin

latest release | view in KDE store

Extension for KDE's window manager to make windows non-overlapping, by automatically minimizing a window when it gets covered by another window, and optionally restoring it when space becomes available again.

This is intended to keep the workspace clutter-free while maximizing screen real estate and retain the user in full control over window and workspace management, aiming to combine the efficiency of a tiling layout with the flexibility of freely positionable floating windows.

Note that this script is an extension to be run on top of KWin and not a standalone window manager, and will also not do any automatic tiling.

The windows to be affected can be filtered by window type and application.

By default, any window that has been automatically minimized will be automatically restored once the space above it is free again; this can be disabled in the configuration.

Installation

Dependencies

kwin (tested with version 5.26 on X11).

Installation via graphical interface

1. Install the script via Discover or System Settings > Window Management > KWin Scripts > Get New Scripts … > search for Floating Tiles > Install.
2. Enable the script by activating its checkbox, and apply the settings.

Installation via command line

git clone https://github.com/nclarius/floating-tiles.git
cd floating-tiles
./install.sh

Configuration

System Settings > Window Management > KWin Scripts > configuration button in the Floating Tiles entry.

You may need to uncheck the checkbox for the script, apply the settings, recheck, and reapply in order for the changes to take effect.

In Plasma versions < 5.24, a bug in the KWin scripting system [1] [2] may cause the configuration not to be found. To fix this, please execute the following commands in a terminal:

sed -i 's/ConfigModule/Library/g' ~/.local/share/kwin/scripts/floatingtiles/metadata.json
mkdir -p ~/.local/share/kservices5/
ln -sf ~/.local/share/kwin/scripts/floatingtiles/metadata.json ~/.local/share/kservices5/floatingtiles.json
qdbus org.kde.KWin /KWin reconfigure

To find the window class name of an application: Right-click on the titlebar of a window of the application > More Actions > Configure Special Application Settings... > the pre-filled entry in Window class (application) (if it consists of two words, only the second part) is the window class to put in the script configuration.

Usage

Known issues

• With auto-restore enabled, when using the Minimize All plasmoid, windows that had already been minimized automatically will be unwantedly unminimized.
• The configuration interface is clunky; buttons do not always appear highlighted as intended.
