Improve Corner Tiling for Multi-Screen Setups

[TheWorldJar]

In multi-screen configurations, corner tiling is challenging when trying to place windows in corners where screens meet. Instead of snapping to the intended corner or edge, windows often attempt to tile on the adjacent screen, making precise placement tedious.

This differs from Windows, where screen boundaries naturally restrict dragging across screens, allowing windows to snap more intuitively at screen edges and corners. This feature can be considered for Linux Mint, though it simply moves the point of friction to another area.

Here are a few possible solutions to consider for enhancing the tiling experience:

• Optional Screen Lock Key: Introduce a function key that temporarily restricts the mouse to its current screen. Available either globally or only while dragging windows.
• Tiling Keyboard Shortcuts: Allow users to tile the active window directly to any edge or corner on the current screen using keyboard shortcuts. Fast & precise.
• Screen-Bounding Option: Add a setting to automatically restrict dragged windows to the current screen boundaries. Like Windows, but with the possibility to turn it off, letting the user choose their preferred behaviour.
• Enhanced Corner Snapping: Improve or make programmable the snapping range for corner tiling.
• Smart Empty Space Tiling: If a window is already tiled on a screen, dragging a different window to an empty area could auto-tile it to fill that space. Similarly, dragging a window over an already tiled area might resize it match.

Any of these adjustments would make tiling in multi-screen setups smoother and more intuitive.
