Custom Hot Corners - Extended

A GNOME Shell Extension which allows you to control and navigate Gnome Shell environment through the corners and edges of your monitors. But not just that, it adds many unique actions with keyboard shortcuts too.

This extension is based on the original Custom Hot Corners exetension, but not much of the original code remains.

Features:

• Gnome 3.36, 3.38, 40 and 41 compatibility
• Hot corners with adjustable barrier sizes, both vertical and horizontal independently and usable as hot edges
• Mouse buttons and a scroll wheel can be used as triggers in addition to / intead of hot corners
• Each trigger can be set to work only when Ctrl key is pressed
• Each direcion of a scroll wheel rotation is configurable independently
• Each trigger can activate one of many actions including command execution, workspace and window navigation, window control, power manager actions, sound volume control, color filters (for windows and global), accessibility features and more.
• Preferences window provides an app chooser dialog for "Run preset Command" action configuration - easy use as an application launcher
• Each corner's area reactive to mouse clicks and scrolls can be extended both horizontally and/or vertically to cover most lenght of the monitor's edges. If the adjacent corner is not set to expand in related direction, the corner can be expanded to 7/8 of the monitor's width/height. If two adjacents corners are set to expand to each other's direction, then it is 1/2 of the length for each. You can see the result of expansion settings by activation of the Make active corners/edges visible option.
• Fallback hot corner triggers as option - useful on virtualized systems where pressure barriers are supported by the system but ignored by the pointer.
• Various options for window and workspace switchers
• The Monitor 1 settings are always used on the primary monitor
• Corners can be watched for unwanted overrides from other extensions and automatically updated when needed within 3 seconds
• You can set keyboard shortcuts for any actions on the menu.
• You can set up to 4 Custom Menus with own selection of actions and trigger them as an action.

Changelog:

v12 (not released yet): Added actions:

• MPRIS player controls: Play/Pause, Next Track, Previous Track. Works the same way as the keyboard media keys - controls the most recently launched media player

• Open New window

• Move App windows to Prev/Next workspace, Move Window to Prev/Next workspace - allows to move window or all windows of selected application corresponding to the current filter settings to an adjacent workspace

• Move App windows to Prev/Next New workspace, Move Window to Prev/Next New workspace - similar to the previous one, but first creates new empty workspace to which the window/s will be moved Other changes:

• Custom menus adds focused window title as the first item only if the menu contains actions that target the window. Fixes:

• workspace index position not centered in GS40+

• added gschema paths for not dynamically created settings - now global settings can be backed up using Extensions Sync extension. Unfotunately, dynamically created settings directories storing settings of all individual triggers don't have unique schema id, so can not be backed up using mentioned extension.

DND Window Thumbnails

Window thumbnails are scaled-down window clones that can be used to monitor windows not currently visible on the screen. Default position for the thumbnail is bottom right corner of the current monitor. You can create as many clones as you want and place them anywhere on the screen. Each thumbnail can be independently resized, you can adjust its opacity, even change its source window. When the thumbnail's source window close, thumbnail is removed too. The code is based on window preview of BaBar Task Bar extension.

Primary cLick         - toggle scroll wheel function (resize / source)
Scroll wheel          - resize or switch source window
Ctrl + Scroll wheel   - switch source window or resize
