Fluctuating width of the System tray

[sdr0x07b6]

Is your feature request related to a problem? Please describe.

I am creating a timer application system tray for macOS.
I use set_title() to display the time remaining.

Because the width of each number is different, the width of the System tray changes each time it is dynamically updated. The position of the System tray to the left of the timer is also affected by all of this.

Describe the solution you'd like

I don't understand how far the OS can go in terms of potential. However, if I were to mention just a few things that immediately come to mind,

• Allow monospace fonts to be specified
• Fixed widths for the System tray itself

Can you think of anything else?

I looked for articles like this one.

AS this can't be added to tauri v1, I will move it to https://github.com/tauri-apps/tray-icon where it will land in v2
