Set Tab Stops Within Controls that Display Text

I'd like to be able to set and reliably use tab stops of different kinds within controls that display text.

After some experimentation I have discovered that I can use tabs in the current desktop implementation (I'm using 1.6.36) but must include a single space character before the tab or it displays as a single space not a tab. I suspect that this is just a random side effect of the current text implementation but at least it works to some degree.

I'd like to see proper tab support such that I can set tabs at certain locations (whether by pixel position or inches or cm, etc.). Left and right justified tabs at a minimum. Centered and Decimal justified would also be nice.

An example of where I might use it:

Assume I have a series of bold label + associated URLs. I want to align things such that the labels are all right justified and the URLs are all left justified.

I could implement this by using one label and one link control for each set, setting identical widths and right text alignment on on all the labels, but that means two separate controls for each line which must be grouped if I want to reliably move them together but then making changes to the text requires that I ungroup and then regroup them.

Or, I could implement this by using one text string, setting one right justified tab followed by one left justified tab, entering the string as:

{tab}*label*{tab}[url]

This requires just one control per line, making moves and future edits straight forward.
