Issue?
The task tray icon on a UHD 4K2K resolution is super tiny. Need the ability to select different (larger) task tray icon sizes in the preference menu. Today, I must manually edit the the .png file names (e.g., tray@2x.png) in /opt/Wire/resources/app/js/menu/TrayHandler.js to achieve the desired results.

Right!
The icon is too small for me.
