Here is a video showing unread notification numbers up to 21 with this patch. The font settings that affect the unread notification number (general) are at the default settings.

When there are 2 or digits, maybe the circle can expand to become pill-shaped so it can accommodate the increased width? Or maybe the font size should decrease?

The circle comes from Plasma theme, cannot transform it.

The patch makes the position of the numbers more consistent, but it's still slightly to the left of center.

  Does this make it any better?

The numbers seem to be slightly smaller and fit in the circle slightly better, but they're still off to the left a bit, just as much as in the video I posted above.

For example, here are the numbers 1, 3, 10, and 21.

as good as possible

Just an idea: run "kcharselect", type "circled digit" resp. "circled number". For values <= 20, unicode has pre-rendered glyphs.

Unfortunately, there is a jump in size from 10 to 11:

Also, the circle comes from the Plasma theme.

Could we increase the size of the circle in the Plasma theme to make any slight mis-alignment less noticeable?

It might look out of place next to all the other icons which are always 16px high at most (on a 22px canvas). However, I think the misalignment might be less obvious if we filled in the circle and used the Background color for the numbers.

Eh, changing the background to solid didn't help (I did include the changes from this patch) and it looks somewhat out of place next to the other icons.

That might be the best looking solution though: allowing the theme to transform it based on a certain property (in this case number of digits and width)

Should we go with this now to improve the situation a little bit at least?
