UI: button in the status bar for selecting the system of units has a variable width

Is there an existing issue for this?

Problem description

Changing the width of the button continuously shifts the other buttons while zooming the screen. At the same time, the constant flickering of numbers in the lower right corner is always visible to the user's peripheral vision, which distracts from work (I consider this to be an incompetent UX element).

I suggest fixing the width of the button and displaying only information about the selected unit system on it (in an abbreviated version, so as not to take up extra width). Additional information can be shown in the popup hint.

An example from Solidworks

I don't really understand why information about the size of the working field should be constantly displayed, especially in a variable format (is not always correctly translated into other units, situations arise m x km or nm x mm).

But if this information is important to someone, I suggest moving it to the left of all the buttons, so changing the width will not affect the other buttons.

A tentative layout

It is advisable to do this as an option:
