How can I make the gui trey bigger? thanks

[gitdexgit]

I use the trey menu a lot I love if it's so, so useful, most of the time at least. Anyway. I want to make it bigger, do you know where I can do that, thanks?

The icon size is managed by Qt GUI framework based on the desktop environment.

One way to increase the size, is to scale up the whole UI by setting environment variable QT_SCALE_FACTOR (e.g. to 2).

Not sure if there is a better way.
