ShaderGlass v1.1.6 beta

Changes in v1.1.5 beta plus:

• ability to edit global hotkeys
• new global hotkey: Capture Cursor on/off
• new global hotkey: Shader Active on/off
• new global hotkey: Toggle Menu (allows bringing up menu even in fullscreen)
• add Pixel Size slider and Parameters button to Shader Browser window
• fix for dialog windows so they don't get covered behind main window

Not planning any more bigger changes for now, this will likely become v1.2 stable

Thank you for testing & feedback, much appreciated!
